They've had threads before where sigs were disabled. I remember a few cases in the past.
As for the site feedback. Looking nice! I like the uniform look with PS2 UI. I like the detailed touches in the right of the screen where the teal or whatever color isn't perfect but is "smudged"/scratched/something. Perhaps that could be added a bit more or something so that some areas of the page would look a tad more "lively".
I noticed that something regarding the forums functionality had changed. My phone acts a bit strangely with the forums now, but for some weird reason I still can't use tapatalk on these forums with my phone. Never could, still can't, in other places it works though
although I miss the in-game model banner in the top. Perhaps we could have some PS2 models up there?
