Wow you have your hands full. Best of luck with the baby (both of them)!
OK I didn't read about the vote for vote thing as I was in a hurry. I generally don't go in for that kind of thing - there is no way I could vote for everyone that voted for me:)
Well, the one guarantee is that they have my upvote if they post there & I will always be available to advise them on how to optimise.
Not too sure how the vote for vote system will work. At the moment there are 121 members and only around 10 of them seem to post in the group regularly, so to upvote those 10 wound't be much of a chore. But I think we could make exceptions on that rule for people over 70 rep! So, pick and choose. Whenever you have a moment. Your advice would probably be more valuable in the long run than your upvote, particularly if the whole group read your words. Whatever works for you my friend.
All the best :)
