[BACH] BACH's meta chat room

[sunjam at james.network]

Noisebridge is attempting to create a chat room we can bridge to as many 
other Bay Area hackspaces as possible.  The chat room is currently 
available from:

https://matrix.to/#/#BACH:matrix.org
Noisebridge Discord's bach guild
Noisebridge Slack bach channel

It is located within an index for USA-based hackspaces on Matrix
https://matrix.to/#/#USA:hackspaces.org

Noisebridge has a wiki page on the BACH chatroom at
https://www.noisebridge.net/wiki/BACH-chat

Help us test, tweak and improve it!
