The Shoutbox module provides an interface for users to quickly post messages that are viewable on any page an instance of the module is located.
How to use the Shoutbox (Admin)
First, create an instance of the module. You can then set a few options for the module: Number of shouts per page: The shoutbox has multiple pages that users can parse through to see archived messages. After this limit is reached, the oldest message on the current page will be moved to the previous page to make room for the newest addition.
Post Access: This determines which users can post on the shoutbox. The default is "All". It is recommended that you change this to at least "Registered Users", otherwise you may see an influx of random posts from anonymous visitors on your shoutbox.
Moderation Access: This determines which users are able to delete posts on the shoutbox. By default, this list is clear, although the Site Owner and Administrators will be able to delete posts.
Once the shoutbox is made to your satisfaction, you must place it on a page. Use the [Pages] tab and find the page(s) you want the shoutbox to appear on. Then, in the Layout Editor, create a Container for your module. Finally, click the "Add Module" link and choose your shoutbox module from the list. Users will now be able to view and interact with the shoutbox on the page(s) you placed it on.
How to use the Shoutbox (Users)
Posting is done through typing in the "Your message" text field and clicking "Shout!". Once you post, the shoutbox will automatically refresh on your end. Other users will have to refresh the page, post, or refresh the shoutbox to view it.
For those with the appropriate privileges, moderation can be done by clicking the small "x" on the top right corner of any offending post.
