Re: Which is why I always turn off email sigs...
People should have to go on a course to be allowed to use anything but plain text emails, with annual refreshers so they don't forget how not to email.
People are amazingly fast at forgetting/utterly incapable of remembering. A year would be several epochs too long.
The only way to fix this would be to have their keyboard explode when appending a .sig that's over the limit, or unlicensed use of formatting.
