Next week we'll arrange a Vaadin Developer Meetup on March 11th in London, UK. The core of the relaxed developer-to-developer event is discussions about Vaadin roadmap, future development and showing each other what has been done with Vaadin.
Just drop in for a chat with fellow developers, rant about the most annoying bugs in Vaadin, praise the killer features and get to know each other. The meetup is organized during QCon conference, but it is free and open to everyone.
