Today the new invite system for registrations has been activated.
What this means is that in order to register a new account, you will need to input a valid invite code during registration. This can be activated by anyone, and given by anyone. They are one time uses, and they cannot be transferred between users.
As well, if the user that uses an invite code is then banned for doing something stupid, the user that gave them the invite code may also be banned.
I will be giving out invite codes periodically, as well as giving them to users to give away to friends. You can see your current invite codes in your invite settings page.
Let me know if you run into any issues!
edit: I have given every user 1 invite code to start off with. Have fun!
