GeoServer has acquired a new homepage, made sooner by sourceforge dropping support for mysql 3, which our old postnuke page relied upon. We've been in the process of porting to a wiki for awhile, and are close to done. The location of the actual wiki is a bit weird, so we just decided to use http://geoserver.org to point you in the right direction. Soon we'll get that domain itself up to snuff. But please check out the new page, and please give us feedback, or things are wrong, just fix it up yourself!
