On a regular basis Microsoft and its partners host Free IT Camps. In the past I’ve blogged about them because I really think they’re a good way to quickly get up-to-date on products and technologies. Besides that it’s also a good way to get to know other people.
On the Microsoft Events website you can see which future events are available and not just IT Camps events.
Also should you not be able to attend an IT Camp, for Server 2012 you can also use IT Camps On-Demand.
