All the links at the top are oddly spaced. Home Help and Game Info are pretty far apart.
Game Info and Search are closer together, but not overlapping.
Search and Media are also pretty far apart.
Media and Profile are pretty close together, but not overlapping.
Profile and My Messages are pretty far apart.
Messages and Links have the last letter 's' and the 'L' overlapping.
Links and Members are pretty far apart.
Members and Auctions & Sales are closer, but not overlapping.
Auctions & Sales and Logout have Sales and Logout overlapping. The first letter of each word is in the space location..
I'm on Win 7 Home Premium with SP1 and Auto Updates On using the latest version of Firefox. I double checked to make sure I didn't have Firefox set to magnify pages, it is at 100%. The links at the top don't look to have 'normal' spacing until I shrink things down to 67%, but everything else gets annoyingly small then. I would take a screen shot (is that the right word?) for you but I don't know how.
It doesn't seem to interfere with actually using the links though.
Other than that, I also like the new look.
