Why no download area for FSX missions?

(I've searched on this topic, and have found no suggestion that it has been addressed. If it has, or if this is not the appropriate place to bring it up, I apologize.)
Why is there still no section for downloading user built missions for FSX on Simviation??
They're an entirely new class files to be downloaded/uploaded. They simply do not fit in with ground vehicles and sci-fi spaceships in misc, and they don't fit in with scenery either. They're fun, interesting and rewarding to create and share- so why not encourage their development and use here?
To say nothing of a separate forum for developing missions- think how useful it would be to have a community here of mission developers who would be willing to do 'voice acting' for missions other people are developing?
