We conduct meetings in person when possible and live-streaming on Jitsi at Noisebridge Jitsi.


We are also currently streaming the Jitsi Virtual Hackitorium.

Rooms

There are a few regular and persistent rooms regularly on-line. Any room can be created by just specifying a web path to your name of choice, or by entering any value in to the form on the home page and pressing "Start Meeting" https://jitsi.noisebridge.io

hackitorium

Nominally on-line 24/7 with a feed of the [Noise_Square_Table] from inside Capp St. The weekly meeting is held here Tuesday nights, and there is regular CoHack's Thursday Eve and Saturday Noon.
