Bump! I too shared my track but couldn't find a way to select it when I hosted an online lobby. Not so much longevity from the feature if you can't race them with friends. Hope it gets added as a future feature, seems a likely candidate actually.
Still waiting for an answer. Im guessing we just cant do it right now. Which is retarded. I made a sweet kart track, good straights and technical corners, its a well rounded kart track. Pointless if I cant host a race from it.
