Also, for those of you counting how many spaces are still available - I dont know exactly how it works, this is more my assumption. But from what I remember rd1, it seemed like for US interviews, new dates were created as new interviews were released (again that's what it seemed like, may not actually be the case). If this is the case, then its possible that an interview in a region may seem full , but they will add a new date at some point and open it up to more spots.
Again, I dont know if that is the case but that's the sense i got as I waited to hear. GL
