"Otherwise, you will probably annoy people who hate the chefscotticus script since it lends support to e-mail top-quoting. This includes people who have berated it on a public forum highlighting the new script, apparently oblivious to the fact that chefscotticus's idea for revision was sufficiently popular to receive ~1000 downloads in one month."

Hahaha. Where are said people? I want to read their vitriol!

I, for one, would love to see the floated signature functionality incorporate into the original Gmail Multiple Signatures script. I'm not nearly good enough to keep the chefscotticus script up to date with Gmail (Michael Devore's been great about that), and would have no problem seeing my script go poof.

(Who knew that such a simple idea could generate such vitriol? I can't wait to google it and find out.)

Sure, Michael. I have no priorities other than for the script to be as useful as possible to those of us using it. Feel free to add/modify as you see fit.

Per request below:

31 May 2007: Updated documentation with script to better reflect where the user must edit the script to use it.

Per Andrew's prescription below:

18 May 2007: Updated to reflect changes in Gmail's code. Replaced all instances (there are two) of "window.frames[0]" with "window.frames[1]".

Hacked version that inserts signature *above* all quoted messages (instead of the end of the email body): http://userscripts.org/scripts/show/8411.

(Also has options for posting signature at top of email body.)
