Boast 15 different classes and 17 races. This means hundreds of combinations of races and classes!

133 to be exact. Or where is my dwarf invoker? You should change the hundreds since it smells like BS to a new player, particularly one that rolls something like dwarf or orc.

Also, should it be mentioned in the main page that the game is text based/MUD?

There should also be a how to play page link in the left sidebar. Then, in the how to play page you could explain how to play the game, have a few links to MUD clients such as MUSHclient and the connect button could also be there.
