Okay, so I accidentally logged in and forgot to untick the box that says auto-login... So even if I sign out, when I come back, I'm logged in.
This is no good.
If someone happened to look through my (non-eraseable) history, they would be able to come in here and post as me.
Now I'm not really concerned about someone finding matazone listed in my history, but I don't want them logged into my account.
