The Message View
The Message module comes packaged with a Message view (see below).
Given there is no web form to create or edit an individual message, there is also no built in form to view an individual message. However, the Message module is built using the Entity API and Ctools module and it is packaged with a default Message view that lists messages at /admin/content/message (alongside nodes and comments).
The view renders a table with a timestamp, the message text and the user associated with the event that generated the message. Here is the most basic example with the language set to English.
Here is the same example but in French. It represents the same message as the one above (note the identical time stamps) but in an alternate language. See the Message Schema for an illustration of how the message text values in different languages are stored in the field_data_message_text table.
