There was a post about updates in G+ that impact HOAs - do I need to download those updates on each computer I'm using (I was going to call in on at least 2 different computers with 2 different G+ accounts).  If I need any support while setting up tomorrow morning at about 7:30 am EDT, will anyone be available here?  Probably not the West Coast folks (nor John Brown in Hawaii!). Anything I need to do to prep before tomorrow's all-day coverage of Water 2.0 on Earth Day via HOA???
