In Community 1.0 we had the Technical Users group and the Business Users group. Each of these 2 groups had a file-sharing apps where you could find all sorts of docs, whitepapers and links to videos.

When we released Community 2.0, we restructured it using a more product driven approach. We have now moved all the files in the relevant Community groups. One minor side-effect is that we were not able to keep the number of downloads each doc got so far... But all docs, files and content has found a new home based on our new structure.
