Darn it CO, just when I was going to call you an amazing technoid again... but that did not work for me.
First off, the box to check/select the message I'd already deleted is not there for messages I've already deleted , & choosing the delete option under moderation tools said no messages were selected.
So then I still wanted to test your method on a message I had not previously deleted (I chose one of your messages, LOL). It now says this for that entry:

This message has been deleted by FamilyMan
Reason testing 1 2 3
So its still not deleted, though the actual text of what you put there is indeed gone.
You can access my visitor messages; come look for yourself. Let me know if you see something different.
