Create an account with a username/password. This site is not secure, so don't use a password you use for RL site access.
The registration asks for an e-mail address, but there's no need to provide a real one. Just use some garbage data in the correct format.
Agree to the terms of service, laughable as they are. I didn't write them, it's a boilerplate template.
This is important:
LET ME KNOW THROUGH DISCORD THAT YOU HAVE REGISTERED, AND GIVE ME YOUR USERNAME.
I'll grant you permissions so that you can actually see the site content.
