Very clever and fun, but when I try to change the jpg pic, it comes up with this thing about the fact that it can't find some "f" file, and this "unexpected error" closes down the program. It says it can not find "f" from assembly. It also has 1.0.3118.40332.

Yay, been waiting for something like this. Works great so far, I hit the Spam button and all the laptops and phones in the house all got the message. I haven't tried it in a "big" environment yet, and only with the "text" file, but worked great.
