There is something missing from the group tools that I didn't really notice until I began using them today. Groups need "Documents".
I realize that we can attach a notecard to a "Notice", but that only persists for 30 days. There should be a "Documents" tab, that can link notecards to groups, and allow these "Documents" to be created, edited and removed by any group member who has the correct permission for the respective action. This would be infinitely useful.
For example, a group could publish its mission, its rules, a background on what the various roles are used for, etc. These "Documents" could then all evolve over time, and be accessible by any member who has a permission to read documents. Maybe there could even be different security levels on documents, so they could be set for everyone or only people in a certain role.
The documents may also be useful to simulate something that will be lacking in Second Life very soon, a central discussion places for residents. Maybe residents could edit a "discussion" document to simulate a forum. Notices are great for talking AT members, but we really need ways for members to be able to talk WITH each-other.
