The agenda roll call has two issues:

1. While taking roll call, there is traffic between client and server much more 
than is needed. The client receives multiple refreshes of the roll for each 
participant. It is difficult to tell why the screen is refreshing. It's strange 
that the entire roll refreshes several times. I'd like to review the code and 
perhaps simplify it so that each participant tick box generates a single 
message to the server and a single message back. Maybe I'm dreaming.

2. Once participants are added, there is no way to remove them. They continue 
to appear like zombies. Fixing this will require some design work. We might 
need to keep track of:

participants who are in the agenda and not yet marked as present
participants who are in the agenda and are marked as present
non-participants who are in the agenda and were incorrectly marked as present
participants who are not in the agenda and are marked as present
non-participants who are not in the agenda and were incorrectly marked as 
present

In the attached screen shot, I made a few attempts to get David Fisher onto the 
agenda with sad results.
