Loving your profile pick. to change your link to be all pretty. when you edit your sig, instead of pasting, use the insert link button above the text box on the right. it will pull up a text box, enter or paste the link there. hit enter or ok, you will notice that some text is highlighted. start typing what you want it to say, hit enter. then preview sig. If its what you want save. if not just re high light the text that is not the url and enter to your hearts desire*.hope this helps.
