It says I don't have a blog (but I do). But I can't find any way to add it.
I'd also like to edit my signature that appears when I post in the forums. How do I do that?
[Moved from the Lounge (which is where you can "connect with your peers" from across all of Adobe's products for conversations that don't directly relate to help and support) to a product-specific support forum by a moderator.]
That bit is not saying that you don't have a blog; it's saying that you don't have a blog via the Jive forum system that Adobe is using. Adobe hasn't activated that feature of the forum software. Why it still puts the blog section in the profiles, I have no idea.
And, as far as I know, you can't set up a signature. There's no need for a signature, really. It's easy to see who's making the post since it's got your name right next to it.
