I thought this was worth mentioning...
I tend to run my screen at a low resolution of 1024 x 640 on most days. The forum window doesn't quite fit on the screen terribly well at that resolution. I don't think the window can auto resize. Should it? For me, 1280 x 800 seems to be the ideal resolution. (That being said, it looks fantastic.)
This seems to be true for Chrome, Firefox, and Safari.
I will look into it.
I have set it at around 1200 resolution.
