Re: PID meeting 14/15 of May




Hi Elke,

 From Indiana, Beni, Alex, and I will be there.  Mihajlo will  
certainly join in discussion by phone.  We will have a local mtg.  
here Wed to evaluate our progress and discuss our talks, but they  
will be along the lines of what you suggest.  We can then give you  
names/topics of people to put on the agenda.

-Matt
