I've been a contributor on these forums for around 9 years using my work email address. That address hasn't changed. Only now suddenly I have a newbie profile with no content. (and no links to discussions I've been contributing to.)
The only thing that's changed is back in March we switched to Federated/Enterprise IDs for licensing the Creative Suite.
Still, as of August I was able to log into my old profile with my email.
Just this week I was following up on a post and I was prompted, at login, to create a forum name. I tried my forum name, and it told me it was "in use." I tried multiple variations of my name and they were all in use, and ended up settling on this one. I now have no way of logging into the old profile, since I'm still using the same address.
Adobe switched to new forum software last week. The concerned team has been notified of problems with usability, botched screen names, lost discussions, missing profiles, etc.... It remains to be seen however if any of this is fixable. Hopefully we'll know more in the coming days & weeks.
