Hello,
I just started to write some script.
I have already my first question: How can I make a new line writing a text?
My Script:

iOriginWnd.SendMessage("Test1
Test2");

This doesnt work! Is there any special command for that?
(It shouldnt write 2x, like:
iOriginWnd.SendMessage("Test1");
iOriginWnd.SendMessage("Test2");




Question Number 2:

I want that when contacts say "you are dumb" that it will be hided. How I do this? (So I won't receive that message)


Question Number 3:

I want the thing from number 2 only work for 2 contacts. How can I check their email with a script?
