May I have a signature below my posts?

Well so long as they are not comprised of 900 photos of Marie Ashby and Central News then of course. You can set this up in the profile section of the user control panel. The full rules are pretty much those of the other place:

• Plain text of about 4 lines or under
• Non-animated pictures of about 300 x 60px or less
  
• And make sure you upload your image to a site that allows hotlinking, unfortunately we can’t host your signature ourselves.
