Hi Silas, I just asked the same question a few days ago, lol. You go up to the User CP up at the top of your screen, in the purple...click on that, click on edit signature I believe it was...then it will show you an example of one of those. Just click on that and you can make your own. Once you're done making it, copy the information needed (its towards the bottom of the page) and go back to edit signature again...just paste the information there, add any other wording you want and DONE! I screwed it up the first time,
BTW, gratz on your fresh start! good luck!
