My roommate has been trying to register for SD. Every time she hits the register button it says that she can’t, because I have already registered. Does she have to go to a whole new computer like at an Easy Everything(a public internet cafe) and register herself a name?
There’s a tiny, little “logout” function on the main page. It’s on the left side of the screen, just underneath all the forum listings.
Thank you SPOOFE, my dear friend 
That did the trick.
