Alberto Vilches vilches@gmail.com Uses the Twitter4J api (with OAuth) to periodically check (using Quartz) for new followers and unfollows, and trigger events to send emails/direct messages or whatever you want. Checks your timeline, mentions to you and RTs of you, and show it in your site with a very simple TagLib. http://grails.org/plugin/twitter-checker Config UrlMappings twitterChecker.CheckFollowersJob twitterChecker.CheckMentionsJob twitterChecker.CheckRetweetsJob twitterChecker.CheckTimelineJob twitterChecker.Statuses twitterChecker.TwitterCheckerService twitterChecker.TwitterCheckerTagLib
