I have been looking closely at how MM's signal each other. I read somewhere that signals are in blocks of 100 i.e. 100, 200, 300, 400, and 500.

I have two questions:
1) Does a signal of 600 or 700 mean anything?
2) what about signals like 250 or 375 or 415 ?

What do you guys think?

My guess is, some use phones, some use volume signals, some use a monthly/yearly lists, some use charts, and some use email.

The only way to REALLY know is to have a friend as an MM.

P.S. If you ask too many questions the MM's will change their strategy, so try not to make it obviouse that you know, just smile to yourself and play the game.
