With the Jive software, you can add announcements in the Jive software itself or in the announcement taskflow. In this recipe, I will show how you can add announcements by using the announcement taskflow. You don't need a special taskflow for it, just the one added in the last recipe.
For this recipe, you will need a WebCenter Portal application with a connection to the discussion services and a page that has the announcements taskflow on it. You can also follow the previous recipe to achieve this.
