Just a few ideas: The Terragen community has a nice setup: links to the software and plug-ins, various member websites, etc. The first link I'd put here are Scott Draves, Mark Townsend (Apophysis) and the Ultra Fractal and Fractal Explorer sites. There is only 1 fractal Free Stuff contribution (that I've found) but maybe putting a link to it would encourage more. I think challenges are a great idea. Maybe the winner could define the next one? Maybe the community could develop a Tips and Tricks section? A while back someone suggested a fractals and poetry coffee table book, maybe the group could collaborate to create one?
