Listeners and Notification
For cases where the built in notification methods like the E-mail Digest, E-mail Notifier and Dynamic RSS and Atom Feeds aren't adequate, Traction supports plug-in listeners (written using the Traction SDK) that can
take action when an article is posted.
Sample listeners are provided in the Traction Software Plug-In Library.
You can write your own listener which will look for a certain type of action, for example when an article is marked done, and take an action such as sending an email to a given set of users.
In another example case, an online newspaper wanted certain types of new articles written out to a text file for an alternate use on their website.
