You are correct on all counts ...
A neutral party has been asked to flip a coin to determine which team will be listed across and which one down, then to pick the #'s one through 10 at random and send me and two others in the group, the teams and the two sequences in an e-mail on Friday evening ... the cc e-mails will serve to authenticate the neutrality and a copy of that note along with a copy of the filled in grid will be sent to each participant on Friday eve or on Sat morning ...
I'll decide later whether it was fun or too much work ... LOL ... right now, I'd like to see the picks roll a bit smoother and quicker ...
