Creative Cloud tutorials

Not that I know of. I do know that once you've established yourself here in the community, you could be asked to contribute (and/or join the ACP program by getting nominated by someone).

You can, of course, post your step-by-step tutorial or tip here; you *can* link to third-party sites *but only if* they are relevant *and* if it's not covered in the official Adobe help. (More here: https://community.adobe.com/t5/using-the-community/adobe-support-community-guidelines/m-p/4788157.)

A lot of eyeballs come here, so I'm surprised it doesn't happen as often, other than Pattie F's tips and tutorials.
