My sig pic no longer shows up. I went to the User CP and it still shows up, but not in posts. Yesterday I added my location because that somehow disappeared, but I didn't touch the sig. Any ideas?

Sorry if I am telling you something you already know...

Try going to "User CP" ---> "Change Signature" and then click "Enable my signature in all of my existing posts." below the box where you enter your signature.

That did it. Thanks, TheEast!
