Hi Matt,
Wayneg90772615 is right in many ways. The commission l'pricing isn't inspiring enough!
As for me I have many great issues with Fotolia/Adobe Stock.
I submit to many image stock companies contributing Illustrations, Painting, Footages and Photos but somehow I found out that Fotolia and Adobe lacks a lot of things that could inspire me to contribute more. I earn a lot in one site compared to here and I continue to enhance my portfolio there. Why it's hard for me to continue submitting here are some reasons, maybe you could help solve:
1.Lack of detailed submission tips. I don't even know if Fotolia and Adobe accepts editorial images and if accepts, how to do it?
I get to know a Middle-Eastern company that didn't subscribe to Adobe Stock because it lacks images from Middle Eastern countries. For one thing, the collection is clearly behind from other stock sites, sorry to say that. I could help submit Middle Eastern themes but somehow I'm not inspired to do so because my images are mostly the editorial kind.. Editorials sell like hotcakes.
2. Fotolia and Adobe Stock combo is so complicated to understand. As a great tech company, why isn't easy to synch Fotolia and Adobe Stock. I still need to find some links out there in order to solve this synching problem but I'm still in a limbo. I'm still confused even I read the FAQs. They are so technical. No simple explanations.
3. Fotolia and Adobe Stock is kind of risky. What if Adobe decides to dump the Fotolia brand in the future..What will happen to the contributors who can't synch Adobe Stock. I'm afraid I can't access my portfolio soon if one needs to access them using anAdobe ID via Adobe Stock. There's no prompt even for me to sync.
4. slow sales... my 1 year earning in Fotolia/Adobe Stock is only 1/4 earning value of my monthly earnings from another site. Could it be buyers are also confused with the Fotolia/Adobe Stock tandem or the lack of image due to uninspired contributors like me?
5. The UI in Fotolia is somehow not user-friendly, boring and many buttons are so confusing. As a contributor, I'd rather see $ sign instead of the word credit. One time, I have to take some earnings from my site and transfer it to paypal, but it took me more minutes to understand how much would a credit give me when converted. It took me sometime to research for it. In the other site, it's so convenient, that you don't need to convert credits.. payment is sent as $ with an advance email of what or how much I will receive.
6. Oh this one is important... Why can't I reedit my Titles and Keywords of my uploaded images?.. I can't add or substract or correct keyword spellings once I submitted them. There is no tutorial on how to do it. Once uploaded, it seems the titles and keywords will remain the same forever and can't be altered.
7. I don't know the geography/user of the downloader and how many uploads in a day ( a daily record that could help me inspire to contribute more)
8. Also since the tips in the site lacks details, may I ask if people whose faced are not recognizable in the photo or their face are not clear back are ok to submit? Is it possible to be sold and no need of model release?
For now, these are the few suggestions that hope could help assess the current situation I'm in.. I'm nothing against the site. Just want to share my contributor experience to help improve that experience 
regards,
george
Thanks for the feedback George!
1.Lack of detailed submission tips. I don't even know if Fotolia and Adobe accepts editorial images and if accepts, how to do it?
We do not accept editorial content at this time.
2. Fotolia and Adobe Stock combo is so complicated to understand. As a great tech company, why isn't easy to synch Fotolia and Adobe Stock.

If you were an existing Fotolia contributor before the Adobe Stock contributor portal was launched you would have needed to sync your Fotolia account to Adobe Stock upon your first sign in. If you created a new Adobe Stock account from scratch, you cannot add your older Fotolia account to it. If there is no content in your Adobe Stock account, I can unsync it so you can start over and sync to Fotolia.
3. 3. Fotolia and Adobe Stock is kind of risky. What if Adobe decides to dump the Fotolia brand in the future..What will happen to the contributors who can't synch Adobe Stock. I'm afraid I can't access my portfolio soon if one needs to access them using anAdobe ID via Adobe Stock. There's no prompt even for me to sync.
All of your content uploaded to Fotolia is available in Adobe Stock regardless of whether your synced your accounts or not. The opposite is true as well. If you upload through Adobe Stock, your approved content is available to Fotolia customers also.
4. slow sales... my 1 year earning in Fotolia/Adobe Stock is only 1/4 earning value of my monthly earnings from another site. Could it be buyers are also confused with the Fotolia/Adobe Stock tandem or the lack of image due to uninspired contributors like me?
I can't speak to your earnings at other agencies. I can say that Adobe Stock is doing very well and sales are increasing at a rapid pace. We have an exceptional sales team working hard to drive sales for contributors and we offer the best product and experience in the industry! The vast majority of creatives in the world are using Adobe products. Your stock content is just a click away from within the apps they are already using. Create new, relevant stock content and submit on a regular basis and you'll find the potential to be limitless.
5. The UI in Fotolia is somehow not user-friendly, boring and many buttons are so confusing. As a contributor, I'd rather see $ sign instead of the word credit. One time, I have to take some earnings from my site and transfer it to paypal, but it took me more minutes to understand how much would a credit give me when converted. It took me sometime to research for it. In the other site, it's so convenient, that you don't need to convert credits.. payment is sent as $ with an advance email of what or how much I will receive.
Using the $ sign for credits will be convenient only for US based contributors. We are an international company dealing with many different currencies around the world. Credits are our universal form of currency. For US based contributors, 1 credit = $1.
6. Oh this one is important... Why can't I reedit my Titles and Keywords of my uploaded images?.. I can't add or substract or correct keyword spellings once I submitted them. There is no tutorial on how to do it. Once uploaded, it seems the titles and keywords will remain the same forever and can't be altered.
You can edit your keywords and titles in the Adobe Stock Contributor portal but not in the Fotolia UI. You will need to sync your account to make these changes.
7. I don't know the geography/user of the downloader and how many uploads in a day ( a daily record that could help me inspire to contribute more)
Your sales page shows how many images you sell in a day. For privacy reasons we are not able to disclose buyer information.
8. Also since the tips in the site lacks details, may I ask if people whose faced are not recognizable in the photo or their face are not clear back are ok to submit? Is it possible to be sold and no need of model release?
Yes, if the person cannot be recognized or recognize themself from the image you can submit it. It's important to note that a face is not the only thing that could identify a person. A unique scenario, tattoo, birthmark, hair style, etc can be used to identify people. Additional information about model release requirements can be found here: Model release and protection guidelines for Adobe Stock
