I presume that when all we see in the text is "MESSAGE" it means the forum's filter has deleted the original text. If that is the case then it can't be rocket science for the filter to check whether all that is left is the word MESSAGE and if that is the case just delete the topic (and the user id of the sender).
Dennis, you'd have thought so. This software seems frustratingly limited. We are trying to work out how to make a change without losing all the good stuff already on here.
