How can I set a footer line
 

on my messages that shows up each time I post. I figure it's somewhere in my profile, but I have not been able to find it.

Click on "User CP" (up and to the left of this area, in the horizontal navigation area), then click on "Edit signature," which you'll find in the navigation area that runs down the left side of the page, under "Settings & Options."

Word of advice: Don't use "Don't miss the boat, be sure to quote" as your signature unless you want a lot of unintentional comedy.

Thanks! Just couldn't find it...and this should be my first post with my new sig (though the site is still a work in progress).

Rob's answer is spot on and i can't make it any more clear...

got it! I had a problem with the database on the site earlier today, but I think I'm good now. Appreciate the help. The site is still a work in progress but I might have it mostly done this weekend.

Thanks for the thread.
