[G8b_run] g8b question

Wed Jul 20 11:13:31 EDT 2011

Unfortunately, there would be a conflict with the GlueX physics meeting (every other week on Monday at 11:30 AM) if we start the Monday after the next one. Can we have the g8b meeting perhaps at 12:30 PM then or would this be too late? Or start next week and then have it every other week?
