The Message Types Tab allows studies to be classified and sorted under specific types of studies. 

Click on the Message Types Tab. 

On this screen, you may click on the desired icon - delete, edit or new.

Click on the green checkmark to either publish or unpublish a study.

Note:  When a type is unpublished, all the information is still stored in the database, but that type will not appear in the drop-down lists of types.

Use of Message Types is optional.

Enter a descriptive name for each category.  Using a message type is another way to allow users to sort and filter the studies they would like to view.
