Hopefully advances in coding make the following a possibility now.
Current Problem: When composing a PM, unless you click the "Add" button under recipients, when pressing Submit, the preview screen loads. Unfortunately, many users believe there PM has been submitted.
Solution: Replace the "Add" button with what I think is called
an onblur event. (I'm not a coder but I hope that is right.)
This way, the Add button would not be needed at all and the current confusion would not exist.
Thanks to the developers for your continual work,
Pat
