No website should really make you computer SLOW it just all depends on your computer. So just try a bunch of game sites and see what happens
Many online game sites have friend or share codes. You should look on those sites for any that may be posted and that users wish to share. WikiAnswers does not allow any such personal information to be posted here. It is inappropriate to ask on this site for such information. It may also be dangerous and it may be illegal.
Now here is what i think of shelterbelt, I'm a student in the southern US, and there are allot of things that do deserve to be blocked, say, pornography websites and gamesites that show gore and nudity, not to mention bad language. but lets say... Youtube! Youtube dos have a few things that deserves to be blocked, but all videos there have there own port, just close the ports that are not student or child friendly, Youtube dos have many things that they can share with us, but yes, yes, some most don't want children to see, lol. I mean, its a miracle that Wiki hasn't been blocked for me! But here is one reason for shelterbelt, the things that are posted on the Internet come from one source, that means that it came from somewhere in the world (or other world if you believe in space creatures and that stuff.). So i do think shelterbelt dos block a little much, but what if we didn't put that inappropriate crap on the Internet? then there would be no need for it, so if your reading this right now... blame this on humanity's sick instincts to post themselves naked on the Internet.

When loading programs, press Run. If (when) an error pops up, (with a letter and number, like A1 or H2), press select and enter the appropriate code. Gamesites will label the strange symbols 1, 2, and 3 from left to right. If an error doesn't pop up, press select anyway to enter an EX code. Some programs installed via EX codes (Airshoes, Fastgauge, Antidamage, etc.) will cause bugs, while others won't.
