As many times as I find it's better to omit their presence.
BTW, I keep Sigs turned off.
The real question is, why do you hate to think of it? Were you abused by a Sigless person when you were younger? Does my turning them off scare you? Are you trying to esablish me as a pariah because I don't care to see silly sig lines repeated hundreds of times after posts I didn't even bother to fully read?
Oh, and you omitted one of my "t"s.
