I should just say that asking for advice is OK in vote chess, as long as it's someone also playing on your team/ in your group. That's what the team discussion box is there for.

Thanks for that correction, atomichicken. I've now incorporated that in the original table in post #6.
(As you may have noticed, QUOTE does not preserve the formatting of a quoted table.)

Thanks. Would there be any mileage in putting it in some official place where it could more easily be found by searching - and more directly referenced than the middle of a topic? Such as, in this article ... Site Playing Rules: A Guide for the Perplexed, for instance.
I was wondering - are you allowed to read a chess book whilst playing a correspondence game with, say, 3 days per move, that might influence your play? In other words, can you read a chess book to help your play (maybe an opening book on the opening you're playing)
Thanks,
