I found out some things after trying the feedback tab to report the Forum Error:
1) A getsatisfaction account is required to use the feedback. 2) It can be used to create a getsatisfaction thread. 3) It is now appearing on all AG2 pages, not just the user profiles.
As an inference, I think the Feedback tab is to increase getsatisfaction activity, which may be an attempt for the admins to increase activity without using the forums.
This thread can be used to post your thoughts on the Feedback tab.
I guess the Admins just prefer to use getsatisfaction, so they added that to send any thoughts people had to getsatisfaction. It seems like a step in the right direction to me. If they're not going to be on the forums, the next best choice is to be connected to it.
