Im sure this has been asked before but how do I make my sig appear in my messages. 4fit made one for me but I dont know how to use it. Thanks for the help.

 

Go to your Profile and add the link to the sig in your Signature box. Then put image tags around it like so:
[IMG] url here [/IMG]

There is also a checkbox that says "always show signature when I post", or something like that.
