We still have a few tweaks to make to a new chat module, then it'll be turning up here on jamroom.net, just for testing purposes prior to its release, so keep a lookout for that
It would be a module that just 'listened' for the 'daily_maintenance' event (Fired once a day after midnight server time) and when received would search all profiles more than five days old with no audio items. Any found would have the appropriate action taken on them. MOdule creation documentation here - https://www.jamroom.net/the-jamroom-network/documentation/development/26/creating-a-module
