For those of us working with the Glue-X tagger, that time on this coming
Monday overlaps those standing meetings, which occur every other week.
Can we pick 9 AM on another day or move to a week later so as not to
overlap?

Hi Eugene and all,
Let's try to have weekly g8 meetings from now on to discuss this, 
polarization etc. We seemed to drift towards having meetings on mondays 
at 12.00 Jlab time. Is that OK with everyone? - If so can we meet next 
on Monday 25th at 12.00 EST.

Cheers,
Ken
