Scratch

I am making a big game for scratch 2.0 called Motion Sports, which is a game using Video Sensing to simulate sports projects. it is going to have soccer, frisbe, boxing, track, baseball (for more info go to project ideas a it should be on the first page). I don't know if I should make a collab for it because I have finished frisbe (without motion) and have gotten pretty far through baseball. But i don't know what to do...
