Here are some of the best links to some cool ass pages I've come across the past few years...

7th Sphere - a cool hacking sight!
Offical Offspring Sight
8 Ball's Chat Room - a great chat sight, but crowded a lot
Cheat Sheet - For school essays and reports already to go!
Alternative Offspring - an Offspring site, in my opinion, better than the official one
Ryan's Skate Page - A great skateboarding page
The Gag Room - A funny sight that talks about everything from Adam Sandler to Shit
The Goddamn Webpage - A funny goddamn sight
Remailer - Anoymynous email !
Midi Farm - A lot of great midis
Another Midi Farm - Another great place to check out for midis
Punk Mania - A great place for pics and midis of punk bands such as Green Day and, of course, Offspring
Always Riding Skateboarding - Another great skateboarding sight
Metal Up Your Ass : The Why Rap Sucks Page - If you hate, rap, go here. Its the best anti-rap website I've seen.
Skates On Haight - The place to buy a board over the net!
