The last wiki was before my time, but I'd certainly second that motion

I'd happily help set this up, and host it myself even, with linkbacks here for reference, for the kudos (and some affiliate bucks...) and I'm sure a few others would also be glad to do that.

But I'm not sure anything other than a new Renderosity hosted wiki would cut the mustard...

...which I guess means Renderosity web dev staff time etc. would be required to do that?

But, maybe setting up a Proof of Concept at least using MediaWiki or similar would be worthwhile? (e.g. to make the case for usefulness and likely user hits)
