The Torrent Upload area is where the users are allowed to upload new torrents when they group allows it. Please see the sample image below.
The upload form makes some basic verifications before submitting the torrent to the server. The "Torrent File", "Category" and "Description" are mandatory. It also allows to link to a post in the site forum (for discussion) and to an info site (in the sample above it's used to display the concert information).
