Which is why I always turn off email sigs...
Maybe it's a hold over from Usenet days, but I hate (email) sigs.
My "favorite" were those idiots whom had half a megabyte of sig attached to an (email) message that amounted to "Ok, thanks, bye."
Oh, and if your sig tries to intimidate the recipient into deleting the missive under pain of legal punishment, you can take your sig & stuff it _RIGHT_ up your arse. The recipient is under no legal requirement to do any such thing. In fact, if they decide to forward it as a BCC to the entire Gmail, Apple, AOL, Microsoft, & EU email owners as global spam, there's not a damned thing the sender can do to stop it.
Email sigs: Just Say No!
