I'm happy to announce the 1.0 beta1 release of workflow-ng. Workflow-ng allows one to customize drupal's built in workflows in a very flexible way. In short, it's a rule-based event driven action evaluation system. Read the introduction to see how it works. It is useful for
- sending customized mails notifying your users about important changes
- building flexible content publishing workflows
- creating custom redirections
- and a lot more....
