VMware vForum 2015
VMware has a history of including community in everything it does, which probably has in no small way contributed to the company's success. One of the many things they do to invite the IT community in is their vForums. These are like mini conferences that are held virtually so that everyone around the world may attend. The next one is on May 21st and is only a half a day. Just like at a physical conference, there will be speakers, labs, and of course prizes.
If you're interested in attending click the link here to register. While it can be a little boring to attend these virtual forums for any long period of time, a half day is probably just about perfect. Plus you get access to engineers in chat sessions and other breakout sessions.
