3 months in -- what have you learned

Many of you have been with this tribe for 3 months. As I've been gone 2 of those due to family issues, I'd love to see where we all stand.

What have you learned about running tribes? How many have been successful, by the standards you set for your tribe(s)? Do you have any pointers that you can offer now that you wish someone could have offered you 3 months back?
