There is no problem with getting opinions. There is NOT currently a problem with team size. That's my point. There is NO problem. Why does there have to be a solution to a problem that does not exist?
The teams will decide if they get too unweildy and they may well decide to form a second team, if it comes to that?? Which, is how group dynamics work, in the real world and in forums, too.
I understand that Maura is concerned. That gives her the option of asking if someone would like to captain a team. Easy. If no one steps forward, (you would be a great captain, Carrie) just let it ride. What else can you do anyway with a free public forum?
One more thing, if you limit "teams" are you also going to limit the numbers of people who can reply to every other thread?
