The idea of local in-person user groups getting together to "jam" on BIAB would be outstanding.
Possibly another forum entitled "Local User Groups" could be a place users could go to post their location and willingness to form such in-person groups.
Individual contacts could be made via PMs so contact information would not be made known worldwide.
In larger cities, the groups could even come together re: specific genres of music.
Most of us do or could have BIAB on a laptop so the users could bring their own puters with them and not only collaborate in writing new songs but also share a ton of HANDS ON in-person tips and tricks.
I would strongly urge PG to consider creating just such a forum.
