In my company, we're using a Redmine. And I thought it would be more useful if I could receive some activities(Like creating/updating Issue) via GTalk. Thus I created acts_as_notifiable.

NOTE:

• I added this plugin to directory:

http://agilewebdevelopment.com/plugins/acts_as_notifiable

• Japanse entry about this plugin: http://blog.s21g.com/articles/415

###Repository
