The community of Scala User Groups has grown in the last few years. Now one of the community, Wilfred Springer, has created Scala-Tribes, a neat site [1] to let people find local user groups and provide information on meetings too. A link to Google maps allows you to quickly locate ones close to you.
If you run a user group perhaps you would like to add it to the site so Scala enthusiasts close by can join you.
