In response to Pam's request regarding membership in IAC - First of all let me say that I have thoroughly enjoyed being an IAC member.  My favourite thing to do on BBO is play in tourneys.  Unfortunately the majority of them on IAC are in the daytime and since bridge is recreational for me I preferr to play evenings.  Not only that I like 8 pm eastern but could manage 7 or 9.  What a pain in the neck a member like me can be!
Team games are also high on my list.  Arranging team members is difficult but easier now that there is a set time for games.
My regular partner and I do play in the club one night a week.  This however, is a set game and we normally don't need anyone to spare.  Trying to find a pickup game when there is no guarantee you will find one or if you do that it will last without people going in and out and waiting for someone else to sit is frustrating.
Teaching sessions are something I will try to fit in - if they fit me.  Sorry Oliver, but at this point in my life I don't want to learn precision.  It's struggle enough to try to get 2/1 right.  Weak nt is not on for the partnership I have.  Also daytime teaching is beyond me on a regular basis.
I am not trying to be negative in my comments.  I do hope other members chime in with their thoughts if only to help Pam get a feel for what is happening.  I have met many people through IAC.  In particular the team games foster making friends.  It is my sincere hope that the club will continue.  I am sorry I don't have solutions.  Perhaps an even larger membership would help.
