phunky monkey, you can add a signature and picture in the same place. Once logged in, look towards the upper right hand side of the page for a link
that says 'your control...' - then click on that link. After that page has loaded look for a click on a link called 'edit profile.'
To add a picture look for the 'avatar url' field and enter an url/hyperlink for an image you would like to have appear under your name. Right below
that is where you can add a signature.
