I did some changes in the "account settings"->"edit on adobe account"->"profile/change" and nothing happened to my forum profiles.
Did you try signing out and then back in?
I suspect they are having the usual problem of the change not propagating from the profile to the community forums. This is a known issue that Adobe still hasn't fixed.
I'll let an employee know that you want a name change. Is the name you want in your profile?
More explicitly, what name do you want to appear in the forums? Please reply here.
