I like the new look, though I'm sad you took away the "Who's Online" option.
However, I have a real problem with how the site runs now.
The site as a whole and forums specifically, have a severe memory leak on IE9.
This is what my Task Manager looks like having had 9 tabs open to various places on the site, most were the forum.
I had the same 9 tabs open before the maintenance and it was NEVER like this.
The way it is now, I pretty much can't use the site at all, since it sucks up 80-90% of my CPU.
