Is there such a thing as the schedule of who is going to be on the chat at 7 on Tuesdays?

Tonight there was someone named Lindsay who tried to get people to call her but would not give us a clue who she was (no reviews could be found against her name) but she said she was from Century City at 310-236-0464.

Lots of LE slurs made by some of the chattees caused her to log off eventually.

Just wondering if there is a way to know who is supposed to be on Chat or not?
