@Ian2 - Although at times confusing, the community site (MIX Online) at http://visitmix.com is seperate from the conference site (MIX) at http://live.visitmix.com. Both actually are available year-round. Our site, MIX Online posts labs, writings, etc. throughout the year. The conference site stays up so that folks can watch videos of sessions and keynotes after the event as well.
There is no current plan to pull in the regional events to the conference site, but something I will definitely put on the list for us to consider. Thanks!
