BL:Classes are things that you could be considered good at in blockland. I am an RPG'er because i like making rpg's and at least half of the people like them.
Some classes are:
Epic-Builder ;"; This class is for people that can build extremely detailed large epic builds.
RPG'er ;"; This class is for people that build town's, castles, etc. and role-play on and/or in them.
DM'er ;"; This class is for people that can build good death-match battlefields or is extremely good at gun fighting.
Gamer ;"; This class is for people the make mini-games of some sort, including races, capture the flag, etc.
Scripter ;"; This class is for people that mod Blockland so that Blockland is either more fun or easier to play.
