how do i create a signature

Look under your name in the top right corner of your screen and do you see "quick links"? Click that and on the left side, there should be a link that says "signature".

 

LOL i did it the awkward way and went to my page and then clicked customize profile. thanks

 

wow i didnt even know that oh well thanx you just made my life just a little easier

 

If you're looking to actually design your own signature, I would suggest using an editing software like Adobe Photoshop.
If you just want to edit your signature text, go up to the top-leftish area of your screen and click where it says 'User CP' It will take you to another page, on the left, click 'Edit Signature'

 

This should have been moved ages ago. Requesting.
