There are a few telegram groups for meetup organizers, if you DM me your telegram handle i can try to get you added to them.

I just hosted the 22nd Western Mass Bitcoin Meetup and here are some things I've learned.

1. Most importantly is consistency. Pick a frequency (most are monthly) and stick to it.

2. Meet your members where they are at in terms of their Bitcoin knowledge. If you are speaking to a group try to answer questions or make points that are technically correct but can be simple enough for new people to understand.

3. Meetup dot com sucks, but it seems to be where almost all the Bitcoin meetups are listed. But definitely check out nostr:npub1ve8qwrlztemdmnh62jffcr0y9m9dpqgqjdg8ufx7gc3qw5wdk74qyv9ka6 for finding local bitcoiners.

4. Be Bitcoin only, but don't be toxic. There is enough toxicity online and very few will come back or continue listening to you about Bitcoin if you aren't polite. It's possible to be firm without being toxic.

Good luck!
