This plugin lets users upload files into BuddyPress groups. A simple, install-and-go plugin. You can specify what file formats you accept via the Plugin options.
The initial plugin of Peter Anselmohis is no longer available, and the old version is not compatible with WordPress 3.3. and Buddypress 1.5.
So I start edited it in order to work with Wordpress 3.3. and Buddypress 1.5 and Chris Keeble made a great contribution, since 0.4.3.1 version.
Many thanks to the wordpress.org forum for debugging!!!
