Hi there. I'm so glad you figured out how to get Webrep off Gmail because I'm about to pitch my laptop across the room. (Yeah, that will solve the problem! ;-)
I tried to follow your instructions but no matter what I do, Gmail defaults back to having my signature and therefore Webrep on. I have nearly a foot of this repeated garbage at the bottom of one of my business threads, for example, it tacks a new one on every time i reply. This "feature" is killing me. Can anyone help?
