RavenDB Webinar #1 was announced at: Hibernating Rhinos: Zero friction databases.
From the webpage:
The first ever RavenDB webinar aired last week, Thursday the 8th, and it was a great success. We announced it only about 12 hours in advance, yet 260+ people registered. Unfortunately the software we were using only allowed 100 people in – our apologies for all of you who wanted to participate but couldn’t get in, or heard of it too late.
More videos said to be coming!
