Correct me if I'm wrong, but doesn't TTS only works with open time? One can argue "ballot" status can be maybe sort of a dropped trip, but it really isn't because is not known what is in the actual ballot.
Anyways, I just thought there was a way of picking up a dropped trip without having to contact the other pilot since he/she already dropped it. I guess that only worked with litesabre. But hey, everything that litesabre did can be done else, right...
