PubForum is a conference that is put on by Server Based Computing experts as a community gathering / learning experience.  I presented at PubForum 2005 in Nice, France and it was a great experience.  If you plan to be in Dublin during May 9th through 11th, or if you've ever wanted to go to Dublin, I highly recommend this conference.  The conference costs a nominal €175 so it's not very expensive.  Although with the current weak dollar, that's about 1 billion USD LOL.  It's actually around $260-275 US.
