How do you set a signature?

I don't see how to set a signature. Can someone help me with that.

You should be able to go and view your account. (left hand column). Then edit account.(button at the top of your profile screen). Hope this helps.

Click on your name over in the lefthand column;When the page opens, select the "edit my profile" option;Scroll down to the Signature box and enter your signature;Next, mark the box just below your signature that reads "Always attach my signature"Finally, go to the botom and save your changes and that should do it.Hope this helps :-D

Thanks to both of you.. I got it.
