It seems everyone so far is in complete agreement that is should be a survival server with enemies set on normal difficulty and a max height of 256.
As for the creepers issue I have found the following plugin found
here which would enable me to disable creepers from damaging the world but still let them hurt players and give some control over endermen picking up blocks.
Another question I forgot to ask: PVP; enabled or disabled?
edit: towlie, Elu, and wast are the only ones I know who play minecraft and are still around right now. Until I see how at least one of them votes I can't declare that a majority is in favor of the choices of flying and map status.
