I would like to change my signature in my google apps account so it isn't gray at the bottom of the emails after I send them... Can someone help?

I'm pretty sure all signatures are like that, unless you go html, in which case you can use this greasemonkey script http://userscripts.org/scripts/show/16839

This only works if your account has 2.0, otherwise use http://userscripts.org/scripts/show/6356

If you haven't heard of Greasemonkey before, you should check out http://mozilla.com if you haven't got firefox installed, and then install greasemonkey here https://addons.mozilla.org/en-US/firefox/addon/748

More userscripts available at http://userscripts.org
