OpenOakland has had 4 virtual meetups so far. For our first meeting we tried to use breakout rooms for projects but that was too inflexible. We now use Zoom for our introduction, CoC review, announcements, etc. We then use the Slack Call facility for our projects. Since there is a Slack channel for each project this works well. We leave the zoom open for onboarding of new members. (Given that we typically have had over 30 people at our in person meetings I find the project Slack Calls fix the problem with too much conflicting noise we had at the in person meetings! ) We have had about 20 people at our virtual meetings.
