at first I want to thank you for the great work that you're doing here with the TeamCal!

I have the following problem...
I can´t use the email-function, because of my in-house guidelines. There is no way around.
How can I modify the hole mail thing, to use only announcement?
What I have done is to comment out the email function in the massage.php, but what´s the way for the absences (approval required), etc?
Sorry for my english... I hope you understand what I want.

I wish you a Merry Christmas
Sascha
