LOL! I read that thread earlier today. Great read. LOL!
I would STRONGLY suggest that you use some sort of security, WEP Encryption, MAC filering, etc. Unless you live out in the middle of nowhere, COMPLETELY hidden from the outside world, you're going to have "unwlecome visiters" on your network, guaranteed!
If you don't mind some sicko downloading kiddie porn on your network outside your house, in his car, naked from the waist down, beating off to all sorts of illegal pictures, then by all means, go for it. If you don't mind some pot-head hack0rz stealing your identity along with all your banking and finiancial information, then, by all means, continue unprotected.
Dude, it's like sex: if you keep having unprotected sex, you're going to catch something REALLY bad sooner or later.
Suit up and protect yourself! :approve:
