XPAC ? The wrestler? Where did he go anyway? Were you one of those XPAC is cool fans? Gotta say, still think he sucks.

Anyway...

I liked Preachers tuturial. Basic fun things to do with Telnet. More than just for configuring routers! Everyone who is responsible for administering a network should know it's functionability and it's vulnerbilities.
In XPAC's defense, people who know the ins and outs of computers and hardware, aren't always arawe of simple communication or networking tools such as telnet.

I think Preacher should expand on his tutorial a little bit. Like mail servers behind firewalls. Ways you can be logged. Reasons why a user would get messages such as Invalid route address or IP name lookup failed when putting in a receiver for the e-mail

Just a thought
