That's the next thing for kcbitcoiners.com Since it's a static site, you can host it on nsite for free. Will take 5 minutes of setup. All I have to do is make it generic so other meetups can use it. It's basically whitelist posts from certain npubs. Which I'm gunna add a marketplace listing for nip-05 so you can run a scrupt to detect who donated to the meetup and then they get nip05 and added to the whitelist.
