About the repository idea, I'll insist I think it's not necessary the files hosted at PGD. There are a lot of free hosting sites, as SourceForge, Megaupload, etcetera to do this work, and a lot of us have our own web site as well. I think also is a good idea to allow only regular users for this service, but then PGD will need some moderators to be aware of "trolls", people who post only to gain the access to the repository.
