I have recently been trying to start a vanilla LIGHT roleplaying server. As a light roleplaying server, our players do not need to make a bio in order to get accepted. Everything about your character will get developed as gameplay progresses. Almost nothing is forced in this game. All players can contribute to the story as long as it makes some sort of sense. Want there to be an upcoming battle? Just roleplay it out then! Example: "I came from the mountains and spoke to our almighty samsung god lord of all cellphones. He said we must attack the other tribe at dawn!". The story is meant to be silly at times in order to create a fun minecraft experience. All players have the option of joining on of the two official tribes or wandering off on their own in the wilderness (Maybe even create a gang of bandits to attack other players?).
There is almost complete freedom here. Something that's lacking on a lot of RP Servers. If this is something you are interested in then please reply or PM me. I can offer you the IP afterwards.
The server is a 24/7 dedicated server. At the moment we have no plugins but when bukkit is released stable I will add a few. Mods on this server will NEVER spawn items. Not even for themselves.
