Jitsi is a free, encrypted video conferencing program/app that can be used to safely plan direct actions and other events. Anyone can make a Jitsi meeting. Jisti is primarily used for small discussions or meetings (it does seem to work best with less than 20 attendees in general). Zoom has more flexibility and tools when it comes to large events.
Note: Jitsi and Signal are the more secure option and should be used for planning direct actions, protests, or anything that you would not want a large corporation knowing about.
While the Suffolk DSA Co-working Space is available to all; it is not recommended you use that space for specific direct action meetings and instead make a Jitsi "room" closer to the time you want to meet and send out via Signal to comrades directly involved (either individually or in an already purpose-made Signal group).
