Go to the little square the the top right corner that says you name, hover over it and four options should appear. Click "My Preferences"

Now, go down to the bar and type in (without the space between the first two brackets) [ [User:Obeseman|Whatever you want your sig to be]] (The line after man is shift-backslash btw)

And then fgo down to save sig, and everytime you add four tildes, that little thing will show up and link to your profile.
