i got it to work, and now have an official GM add. most excellent.
PS, is there a calender button yet for toolbar?

not that I am aware of .... if you find one..let me know.. :)_

The other thing is...when you click on 'calender' inside Gmail..it opens a new window. ACK.

Try the Greasemonkey script...
