Well, Quincy, you learn something new every day! I usually take care of member's profiles (including my own) on the back end, and have never seen the siggie question before. I just tried it "the old fashioned way", and lo and behold, there it is! Thanks for your help!
So, jgrumet, go up to the menu in the top right-hand corner of the forum page and click on "profile". From there you will be taken to the page where you can edit your profile. There is a drop down box to choose if you would like to view signatures.
