Why Gmail team doesn't built this function in?
A big problem too, when you answer to someone, the mail is like it :
- your answer
- his/her mail
- your signature

why not :
- your answer
- your signature
- his/her mail
????

Wake up Gmail team ;-)

This works well if you send mail to a Gmail account. But for other mail services, it's plain wrong.

Couldn't a signature be used as an end-of-message to improve conversations? Maybe google could even parse the signatures and create a virtual business cards which you can import into the contact-list. Gmail could then just show someones name with a plus-sign to expand the info.

TOMHTML – I have put that request in probably 10 times.... agreed, that is MUCH better.... also, the ability to use HTML. It looks like this script will finally let you do the HTML part, but I could not get it working right.
