That's been how things were like for ages. Heck, if you're making levels because you want people to play them you've got it all wrong. If your level does get hosted (in some sort of miracle) it was just a fluke of luck in some way. Same with tilesets, if your set gets used it should be considered a miracle of some sorts. Don't think this is only in JJ2, it's everywhere in any game. People should make levels and/or sets because they enjoy it, not because they expect it to be used, you'll be greatly dissapointed.
