The OzoneAsylum is a discussion forum for all things graphic, located at http://www.ozoneasylum.com/ . There are some very talented people there. It belongs to Doc Ozone (http://www.ozones.com/). It also features a wiki dedicated to being a faq - http://faq.ozoneasylum.com/
On April, 11th 2004, it updated to a new software that more or less seamlessly acts as a MergeBetweenWikiAndForum.
It has also spun off a number of sub-projects, including the Gurus Network (http://www.gurusnetwork.com/), a collaborative project to distill the knowledge of the OzoneAsylum inmates. It covers a wide range of Web design topics from graphics (2D and 3D) to coding - both client-side (JavaScript, CascadingStyleSheets, HyperTextMarkupLanguage) and server-side (PhpLanguage, PerlLanguage). It is a growing community adding resources all the time so drop in and have a look around.
