Hi, Not sure who's in charge of planet.gridpp.ac.uk, but we here at Grid-Ireland have just set up our own public blog and would like our feed to be added to the GridPP planet. Hopefully this will enable us to share a bit more of our experience in running exotic stuff like Xen, VOMS, SAM servers, etc. The name is http://gridirelandops.blogspot.com/ Stephen -- Dr. Stephen Childs, Research Fellow, EGEE Project, phone: +353-1-8961797 Computer Architecture Group, email: Stephen.Childs @ cs.tcd.ie Trinity College Dublin, Ireland web: http://www.cs.tcd.ie/Stephen.Childs
