As in each month having a different timing? I might have understood this wrong but won't this mean that, for example the Europe group would have a meeting every 3 months? Please tell me if I'm wrong. I suggest having a monthly meeting per region such that each group meets once a month, for example the first Sunday, second Sunday and third Sunday. As for the day I'd prefer a Saturday as my weekends occur on Friday/Saturday but I understand this is not the norm. - Adham Omran
