Well I am new to this messenger plus live thing and can someone please write me a script that just sends a message to some one when they talk to me when my status is away.

So it says something like this

Joe Blogs says: hi
MicroChip123 Says: I am away soz

I have looked at the auto takers and they are all to complex because of words that have to be said to get the bot to say stuff

Thanks in advance to any one that can help
