Well, we can only hope that GS eventually will fix the disaster of this supposed "site upgrade" of theirs. However, in my opinion this forum had already bombed long before they took it out of the front page.
Really, it was mostly just the same 10 or so regulars posting and chatting with and for themselves. That and the "system vs system" and "best 1000 games for x system" threads every 2 pages.
So for me at least it was not a surprise the forum ended up in the limbo like this.
