Some suggestions raised at the WLCG Management Board are listed below: <P> <UL> <LI>I.Fisk asked for the correlation between “availability as seen via SAM” vs. the “real jobs success rates of the Experiments (via Crab, Ganga, etc)”. <LI>H.Marten suggested that at the Operation Workshop at CHEP the sites should have the top 5 issues for each service. <LI>I.Fisk also suggested a session for feedback from the sites to the developers, in order to improve the services and the software developed. <LI>R.Tafirout suggested that sites should share solutions; sometimes the information is known by others but not easily accessible. </UL> <P> Other topics: <P> <OL> <LI>Results of review of CERN service deployment wrt resilience to glitches / common service interventions <LI>What do we need to operate the WLCG service for LHC data taking? <LI>Cross site problem determination <LI>Top middleware and operations issues <LI>Implications of migration to LSF 7 </OL>

13:30 - 15:30
Room: Sannich
The aim of the User Support BOF is to better understand what the VO expect from the WLCG/EGEE support infrastructure and how they interact with it, in order to improve the processes and workflows and to make the EGEE user support more helpful for the VO-users. This is a follow-up and continuation of the User Support Workshop held in Karlsruhe in March 2007. http://indico.cern.ch/conferenceDisplay.py?confId=11905 The latest developments in the EGEE/WLCG user support will be presented. Updates from the VOs about their support infrastructure are of course welcome.

Concurrent data export and archiving tests
11:30 - 12:30
We still need to show that we can write data to mass storage and export it to all Tier1s and the full nominal rates for all VOs concurrently. <P> This session will discuss the requirements and schedule for such an exercise.
