no, you are the only one asking so far, so no problem at all. Actually, I am thankful for your interest.
Division 3 is a new competition to be introduced in 2010 for the first time in MS. The rules are exactly the same as in Div2 - CPL.
See
http://www.millennium-series.com/downloads/rules.pdf for general paintball rules and
see
http://www.millennium-series.com/downloads/m7_format_millennium_series_2008.pdf for special rules of RaceTo format.
The only difference in Div3 will be, your rounds of play will be not back-to-back, but with several other rounds of other games in between, so you have enough time to prepare for your next round, even with not at all or only a few pit crew.
That's it.
We will offer a TC meeting (mainly for teams new to the MS) on Friday evening for M5 and D3 teams, if other questions arise.
