Proxy sites?

[innerSpaceman]

Yeah, thanks for the warnings, BTD. Now someone just tell me how to do it already. I don't care if it's grounds for termination, since I am two steps from quitting.

I was going to go the route Moonliner outlined, but being able to access LoT from work is not worth leaving my home computer on all day (it has power management issues, but I wouldn't do it anyway).

So, all warnings having been given, what are these proxy sites, how do they work, how do I get it going? I'm a big boy (well, you know what I mean) and I'll takes my chances.
