First you need experienced mappers.
Once people crank out maps that others play regularly, then we can form a map team. Until then, keep honing your skills with practice maps. DO NOT BE DISAPPOINTED if noone plays your map. Continue to work on them. Examine relic maps, especially the singleplayer ones for how to detail. Ask more veteran mappers how to use a tool if you are confused. Make an effort to try and learn yourself. Practice is the best.
