Try this unblocker!

It's new and nobody knows about it yet:

It looks like a lot of school administrator type people have been watching our sources, and are blocking new unblockers pretty much as soon as they're released. So all the unblockers we've posted on this site are probably blocked and any new ones we post from that same source will be blocked very quickly as well. For this reason it'd be best if you try to make your own unblocker instead - you can find instructions on how to do this here: How To Make A Proxy

What is an unblocker?

An unblocker is like a gateway that pass information between the computer you're on and the site you're trying to visit. The unblocker goes to the site you want instead of you, loads the page, and sends it off to you. So the site you want to access only sees the unblocker's IP. So actually you are visiting sites in an indirect way. School filters only see you visiting the unblocker, not the site you actually want.
