BP Group Documents creates a page within each BuddyPress group to upload and any type of file or document. This allows members of BuddyPress groups to upload and store files and documents that are relevant to the group.
Documents can be edited and deleted either by the document owner or by the group administrator. 
Categories can be used to organize documents. 
Activity is logged in the main activity stream, and is also tied to the user and group activity streams. 
The site administrator can set filters on file extensions, set display options. 
Group members and moderators can receive email notifications at their option. 
The group administrator can decide if all members or only admins/moderators can upload documents (Since v0.5) 
User verification for Downloads: when a document is downloaded, a redirect page checks is the user is member of the group (in case of a private or hidden groups) and only then the user can download the file.(Since v0.5) 
For private networks, see the FAQ “I have a members only network. How to disable file download for non members?” .
4 Widgets: “User’s groups documents”, “Recent Uploads” , “Popular Downloads”, can be used to show activity at a glance. If the theme support different sidebars for group pages, the BP_Group_Documents_CurrentGroup_Widget can be used to show current group’s documents.
Contributions by Lena Stergatou, with additional bug fixes and improvements by Keeble Smith (http://keeblesmith.com) and Anton Andreasson work for BP 1.7.
Original plugin author was Peter Anselmo.
PLEASE: If you have any issues or it doesn’t work for you, please report in support forum. It doesn’t help anyone to mark “broken” without asking around. Thanks!
