I've had a problem with one user that insists on using the greater than symbol to quote messages in replies to forum messages.
A typical reply from them would be:
somewordhere
>>>>>>>>>>>>>>>>>>>>>>>>>
quoting goes here
>>>>>>>>>>>>>>>>>>>>>>>>>
and so on. I indented that for clarity, he doesn't do that part.
The net result is the subject line is blank on his reply/comment! I have it set so the reply subject should be automatic but it's coming out blank in Drupal. When you change your comment viewing options to flat unexpanded, the only thing that shows is "by thepersonthatwrotethis" and no subject at all. That makes me think it's null.
Using Drupal 4.6.3 . I've searched Drupal.org http://drupal.org/ with little success. I did see a similar issue posted back in April 2005 that had no answer to it.
Any help appreciated.
