Red99 (the pvp server) is full PVP with coin loot. Any player can attack any other player within the level range (+/-4lvls). See more here about the PVP server rules:

Population breakdown on blue has official and unofficial sources. dmsimard keeps /who count logs and provides those to the community, while CSR has provided two snapshots of Blue population, which have been graphed on the
wiki. Leveling generally has a shortage of tanks, while end-game generally has a shortage of clerics. However, there are enough of every class that nothing is "needed". If a class has a low population, its because its an inferior class (welcome to Everquest, what balance?).
This "Starting Zone" subforum is probably the best location to get you off the ground meeting people and playing classic Everquest. But don't be afraid the use "/tell" and "/who all lfg" in-game. People are usually willing to check out new places!
