After a long time I've finally updated the Appeal Project wiki site. I've changed color scheme to make the whole thing more pleasant to see and changed a bit the logo image.The other good thing is that now it works with Opera on Linux, Mac and Windows, Opera 8.x for instance. It still looking horrible in IE6 but listen, listen: it works great with IE7-beta2. Hopefully most IE users will automatically switch to IE7 when it will be released.
So I'm happy now, the site is working with at least all last version of all major browsers.
p.s. There are a few problems with mainpage name and his link in the navigation sidebar. Will try to find somebody to fix that soon.
