I have been running a little behind on some posts this week. So here are my answers to the above questions:

1. Yes
2. Quarterly or even semi-annually
3. Posts per month- but I think there should be a provision where if someone knows they are unable to post for awhile, to let them make a post of there absence and they could stay in the group.
4. I think a minimum of 3 posts would work, but also that for newer stackers that comments should somehow big figured in since they may not have that much to post about concerning silver and gold..
5. N/A
6. No
7. Yes
8. Yes

Thanks @silverstackeruk!
