Any info on the official dates of the upcoming MMS?

[All Saints Day]

I'd say it's a safe guess to assume it's going to be either 8/21 through 9/3 or 8/22 though 9/4.

Unlike previous mini mail surveys in the fall, this one will not include the Labor Day holiday.

if labor day is not included, it will not start on a friday (8/21).
they normally go sat - fri, sat - fri.
