Forum:Change signature?

In making my profile I used a quote as my signature, like I do on many websites message boards. What I did not realize at the time was that it is more common to use one's username as their signature here on MA; probably due to the fact that otherwise it will be posted anonymously. Now I am trying to change my signature to just my username so that I can be identified more easily and not take up as much space in the pages with my long quote. My question is simply; how do I edit my signature? I can't seem to find the option to edit my profile or this specific aspect anywhere on My Home or user page or talk page or anything like that. Please help, and thank you in advance. (&quot;The needs of the one outweigh the needs of the many&quot; - James T. Kirk 21:06, September 22, 2010 (UTC))
 * In the upper right corner there's a link to your preferences, it's in a drop down menu. The options to change your sig is there. - 21:43, September 22, 2010 (UTC)
