But i don't know about the username, password and email stuff!
bearjedi, i also don't like seeing threads empty. I know one say as many words as you can before a typo that you made.
A username is the name of your account, like Bearjedi.
Password is something that can be entered to acess your account.
Your e-mail is e-mail.
I Support this idea, since most of them are here to vandalize.
In order to do that, we need to protect all the pages, allowing only registered users.
Actually, protecting all pages is a feature still in developement. I saw a user request it on the developers' wikia.
