I have created a Google group aimed towards providing a hub to concentrate specifically
on user created resources for Renoise.
Currently there is very little organization of resources on the official forum.
I have noticed a few posts regarding resource share in which I originally had a community cloud system in mind but had proved too costly.
The main function that comes from this idea is to have resources organized in their
respective categories as opposed to everything setting all in one sub forum.
While I certainly applaud the idea (and effort!) of a central hub for Renoise resources, I think Google Groups is probably not the best solution for this. Groups is a mailing list/discussion forum. What would be needed instead is a dedicated platform that is made for handling file uploads/downloads (like a CMS). That said, I do not have a better (free) suggestion at the moment.
I suppose another good thing about having it on Google groups is that file storage responsibility is kept with the person who shares the resource via their Google drive space (15GB Free).
Or they can link to externally hosted files also
