Hi there!
If you're looking to sign up to DoorParty, I've moved the application process to the BBS. I figured this gives it a more “authentic” feel to the spirit of DoorParty, and also simplifies the entire thing for everyone.
You can find it here using the fTelnet app on the BBS website, or telnet://bbs.throwbackbbs.com with your favorite installed telnet terminal.
Once you create an account on the BBS, the application form and info can be found on the main menu as:
# % apply for DoorParty!
