Previously having been UK based, I haven't been directing people to US based conference information. However, given some of the announcments yesterday about Virtual Server, the fact that Steve B was the person who kicked off the Linux support under Virtual Server at MMS last year, and ClustrMap showing plenty of readership from the west-coast USA, it's worth mentioning this years MMS conference running from 24th to 28th April. Late to book, I know, but there are a few spaces left. In fact, I believe the cut-off for registration is today.
You can find the entire conference details at www.mms2006.com
