UJS has started to get a lot of attention recently and we''ve found we''ve been getting tickets filed on trac that are more like support requests/help rather than real bugs. For that reason, we''ve set up a UJS4Rails Google Group. Feel free to ask questions, suggest features and discuss how you are using the plugin. http://groups.google.com/group/ujs4rails
