If you use GTalk notifications, you may not have been aware that GVMax will attempt to fallback to other type of notifications if it fails to send the GTalk notification (usually because the user is not logged into GTalk).
I have made a slight change to this.
GVMax will only fallback to email a limited number of times currently 10 times. After that it will not fallback anymore until it is once again able to send a GTalk notification.
Prowl and Howl fall backs don't have this restriction.
