As for lore, for the world and so. I guess some of it can be done for your own maps - if maps were requested to be made by you. But on bigger part of writing the world lore I'd happy to write it myself too, though, I can't for it will start to get incompatible with what others would write. And if you'd be writing a lot you'd know it does not feel well when your stories would have to change drastically. One compromise will lead to another and soon you will not be writing your lore, you'd be just writing down the words of others. "Two chefs in the kitchen ruin the meal" Is the saying in my country. Ought to explain everything.
