That's what I mean : when you preview the question, if you post the same title as a previously submitted node, it instead prompts you with something like :
Your suggested node title : 'CGI Question' matched the following existing nodes. Maybe one of the monks has already answered a question just like yours!
- CGI Question by koacamper(type: perlquestion)
- CGI question by Gibble(type: perlquestion)
- CGI Question by kelcey(type: perlquestion)
if it doesn't, click preview again to really
preview your question.
see? or you could do some twiddling to match "cgi.pm Question" or subtypes of the question
