After like two+ weeks, I finally finished the new registration form!!
It's pretty simple but it actually uses a real DB and not Airtable, as well as sends confirmation emails. I'll be implementing a sendy webhook soon & tie in ticketing, prompter, and ships.
You can try it out today at register.hackaustin.net or view the code at github.com/hackaustin/registrations !
This took way longer than it should've...
