Sorry, had to put down demo for technical reasons.
Aind if someone wants to test it, but doesnt want to make a checkout out of SVN, the mod is packed here:
This MOD is still development quality and may contain(well actually it does) bugs.
Known bugs: Users see attachemnts for which they dont have permissions.
Since the name of the MOD doesn't fully describe its functions, Id suggest a new one, any ideas?
