I dont know if this is right, but maybe 8 lines is measured by pressing enter, while the long sigs you see are just long sentences that merge onto another line like this message is now. Just a thought, or maybe mods get previleges
If a signature was entered into the system before i made the change it will remain over 8 lines until that person tries to edit their profile again. Once they try to edit their profile it will prompt them to change their signature to 8 lines or less.
Small fluke, but i dont want to go into the db and destroy everyones signature over 8 lines.
