Why there is no discord server for Tixati and the rest of the applications?
I think it will be more dynamic than the current forum page

Tixati has a built-in dynamic (although textual-only), permission-less and decentralized communication protocol which can be used anonymously, and without accepting a "permanent record"-type privacy policy. I don't think Tixati and Discord users have much overlap.

About once a month I try to join a Discord chat for some reason, but keep giving up when after filling out the captchas they ask for e-mail (temporary mails don't work) AND phone number.
