Hey there fellow members of PlanetMinecraft, lately a friend of mine and I have been working on a Deathrun Map, this whole idea came about when we used to play on a Deathrun Server in 1.4.6, it had custom plugins. But since 1.5 the commands that hey have added to the command block have made this a possibility. I want there to be a lot of arenas, but one problem, two people can not build a lot of arenas. We do have a server but my friend doesn't want random people on his server. So my sollution to this is you guys go onto a creative, superflat world and just build one for yourself, send it to Frostbite10001 on Skype. If your map is good enough to be played you will get full credit for building it.
Thanks
