Guys sorry to chip in late, groupism and associations do not go well with any government...my suggestion is,
1. let everyone from June or earlier only send the mail today.
2. Send it scattered throughout the day, so it doesn't look like a rebellion but a followed the suit kind of a deal.
This will have a more neutralised impact
I think sending it all at one time will have higher impact but not sure if it will be positive or negative. Esp, when it is ouIr security that is pending.
I am open to sending it together and bear the results, whatsoever they are, together....
Let me know.
