Unfortunately the response was a bit more than we imaged for a zoom call. So we closed the free tickets at this point. That said, if you want to keep touch, check out this survey form here.

Signups can't really be a Show HN (Show HN is for something else, take a look at https://news.ycombinator.com/showhn.html), not-signups even less so. You can probably still edit the title.
If you open up the meeting to more folks without requiring a donation let me know!
