I have my sigs and avatars turned off because of using this profile at work. I can't take a chance of what some people might decide to put either place.
I don't turn them back on at home, not only is it a PITA to keep switching back and forth, but it is particularly embarrasing when I forget to switch them back off and log on at work to show someone our thread and there's some huge bouncing boob avatar.
I'll check it out later
