Public Private Swarms?

If I understand the current state of things correctly, there is no such thing as a “public” swarm on Jami, right?

Are there any private swarms that I could be invited to in order to test out group chatting on Jami?

Should I start one?

If anyone is interested, I created a swarm called “MyJamiForumSwarm.” If you want to be added on it, contact me on Jami. my ID is “iamtomte”
