I picked a really dumb screen name when I first registered with the Adobe forums, and it's showing up now when I make comments. Is there any way to change it? And "edit profile" doesn't seem to be the answer.
We're sorry ShimmyJimmy, but you're stuck now with that embarassment of a screen name for all eternity.
Seriously though, you should be able to change your screen name through the Adobe account area. Click on "Your account" at the very top of this screen, then click on "Edit your account information". On that page you should see where you can change your screen name. This is because of the linkage that exists now between the forums and your Adobe ID.
Hope that works for you.
