Thanks for your insight and ideas
Just wanted to express my thanks for the suggestions and ideas. Running an effective meeting really is a bit of a balancing act and developing a sense for when things should be reined in and when an off-topic ramble is productive comes with experience of a given team dynamic. mhm802, your rules list is wonderful and I have been checking my habits against it. And goncalomata -- impressed with your commitment to meeting management strategies (20 books!).
Again, thank you one and all for your insight and ideas.
