I someone has an invite, I'd love to explore it!
I got my invite from a website where people shared their invite links. After creating an account, and using it for a while I also got the ability to share invites with like 10 people or something.
I don’t even know if doing that kind of thing would work today though, given how many spammers and such trawl the internet. Probably some small number of people would grab every invite for themselves, instead of taking only one invite each.
You can include your email in your profile. I’ve done that and I get occasional emails from it.
