What is the message character limit?
With the latest version there are 2 options for the message text:
1. Type in a message into the message box and you have 2,000 characters
2. Load a message from a text or RTF file, you have unlimited characters.
Loading the message from a text or RTF file shows a message with a scroll bar on the right side so that users can scroll to the bottom of the message and see all of the message.
