Thread:Feedback/Stopping bad signatures?/Pseudomonas

I'm working on a guide for newbies. Variable signatures mean I'm going to have to say To leave a message for a user, please click on the "talk" after their username, unless it's a letter in their username, or maybe an odd glyph, and it might not be after their username, it might be before, or superscript, or subscript, or a different colour, and really the best way to find out is to mouse over every character in the signature while watching the address bar (assuming your browser works like that) until you see something involving "User talk". I'd really rather not have to.
