I was wondering since I find there are similarities between a forum and warehouses like that found on the sketchup warehouse, blendswap, opengameart and gamebananas,
maybe there can be a FOS Platform/Framework similar to discourse
that people can use to host for their own community.
The main difference is having pins instead of thread titles. where you can browse by thumbnails
and like a bit of meta data. like author and say if its a 3d model how many polygons it has etc.
