i dont really understand the script. ive downloaded it, i know how to switch on/off, but what does it actually do?

it has to do something with a toast popup, like when someones getting online.

is it when you post a message to someone, that the send message will appear as a toast thingie?

i know, this is very noobish. but this is my first time im related to scripting anyway... and im not englishXD please answer my Question.
