O.k. I discovered the secret of PMs they are special Chatterblock PMs. Nevertheless the other problem of being able to remove any last posting is persisting.
I have confirmed that if the option to delete the last post is turned on the last post is deleted and it does not matter who posted the chatter.
Was the intent of this option so that a user could delete a comment they just made or was it to delete a message you posted last week?
I don't have this turned on myself but a if you want to allow the user to delete his last comment and no one else has posted a message yet you can make the following change.
Down and dirty. All this does is delete the last record IF the author_user=current user ID. If someone entered a comment after the comment you want to delete then nothing is deleted.
