I just became aware of a JavaFX Users Group, and unless someone tells me otherwise, I'm going to assume that it's the first one. It is located in Japan, and I'd like to congratulate and encourage them!
The way that I became aware of this JavaFX Users Group is that hide1080 (a member or perhaps the leader of this group ) joined the JavaFX twibe. Any tweets (from members of the twibe) that contain the word JavaFX in them appear on the JavaFX twibe page. I just started the JavaFX twibe yesterday, so it will be interesting to see if it is a good medium for quickly exchanging JavaFX-related ideas and answering quick questions.
If anyone is aware of other JavaFX User Groups, please leave a comment!
