For those of you interested in "Hacking", there is this incredible site (telehack.com), for play online. The site is a simulation of the Internet in the 80's decade, with all the systems of Universities and Tech companies at the time, BBS, News Servers, and even people connected to those systems are simulated. You can connect to the site from the web browser, or via Telnet, by Port 23, 443, 1337, and others. If you ask me, this is great. Give it a try..
