It's always that the more stable communities have other interests, modding always has its ugly side...
But yeah, the main objective is trying to create a co-operative community which is my motive, so I accept even newbies, and yeah there's a lot of kids aspiring to mod too. I started when I was 13 myself, so I get it. Can take some time before you come up with a solid idea, but starting out as the new kid can be awkward, but you learn a lot if you can get some patience. The community gets split, but floats around in different groups until people find a common goal.
Modders don't often share info, so getting everything documented is often a pain and difficult.
It's only because it'd be too easy for another group to steal credit sadly. It happens, but that is human nature.
