Hey

Iv'e been looking around that post about the hulla-balloo site (the one with the game). And I got all the solutions by myself, up to the one where u had to use telnet. I admit, the solution to that one I had to get from someone. But.... I want to make up for my cheat. My question is this:

How exactly does telnet work? I'm not referring to mechanics. I'm looking more around the line of commands (i.e. GET, POST, stuff like that) It's just, I kind of obscurely understand it when people tell me what to type, but, then again, I don't.
THanks
