Here's a little addition to the tutorial in case anyone is curious as to what it looks like when some of these commands are issued. I have blocked out the server address and password for obvious reasons, but everything else still exists in it's natural state.

You can see there are two messages, then you view the contents of the first message. The first message is then deleted and a list is done again, confirming the existance of only one message.

Hope this helps those of you who are visual learners...
