Thanks Marc for disabling the heavily abused Wiki account creation page
"I changed it so you can't request an account
Instead I have restricted new account creation so that only existing users can
create a new account
You go here:
https://sudoroom.org/wiki/Special:CreateAccount
Then you check the "set temporary random password" and type in the user's
details. They will get an email with their login details and be prompted to
set a permanent password on first login"
