> Signal groups, in particular, are more powerful than you might be aware of, even if you already use them all the time. In this post I'll show you how to:

- Manage large semi-public groups while still vetting new members
- Make announcement-only groups, perfect for volunteer networks rapidly responding to things like ICE raids
