As I said in teh description, I just Stumbled upon this a coupel minutes ago. Got curious. Is it a .hack// RP forum or something like that? I'll be sure to bookmark this so I can ceck back later.

That's exactly what it is. It's a dot//hack roleplay board, set before Legend of the Twilight Bracelet. It's a play by post format, so you write your own story! When you return, take a look around the registration forum. It has a lot of the information you will need.
