So I am really weary of surpassing my PM limit, and I have read the policies over and over again, yet I still don't exactly know how the PM system works. When they say 60 messages within 30 days, do they just mean a constant 30 day period where for every next day, the PM's from the first of the 30 days is nullified? Or, is it done in increments, where the PM limit is reset every 30 days, and how would one know what part of the 30 days are they in? Or is done by the weekly checks, where every week, the previous week's PM's are null? I jsut need to know exactly how to gauge my PM rates.
