I just come across this thread this morning that was posted yesterday (Sunday).
So the answer to the question raised (and the comments):
Hope this hasn't been raised before I did do a search honest
I have contributed to several threads on the last couple of weeks which have turned out to have been duplicate requests or connected to earlier posts. Usually the mod or an observant member has found the original post & given a link. It's a bit annoying to find you have spent time looking for & providing information that another kind chatter had found 2 years ago.
I have no idea of the technicalities but I just wondered whether it was possible, when a new topic is posted, for a message to appear to the poster to remind them to provide a link to any other thread on the same or connected subject?

As far as warnings and things before people post, generally we find that very quickly people tend not to read warnings and just press OK boxes just to get onto the next bit. It could almost be a case of where would you stop with messages before people post. Such as, "Are you sure this doesn't possibly breach a living person's privacy?" or "Are you sure you are not breaching copyright in posting this?". All these of course are virtuous messages to put up before somebody posts.
We have tried out over a number of occasions a "Related / Similar Topic" features. This showed up posts that had similar wording in the title. It wasn't perfect though - especially if there was a word in it common to many posts. Some of the related posts do appear quite bizarre quite often too (which can bring up some other interesting topics anyhow).
The biggest difficulty was that the feature was pretty heavy-going on the web server itself. As you can imagine, each and every post resulted in a search of some 5.1 millions posts. This caused a slight delay in pages loading up at times and was prone to pages occasionally timing out.
Some of you may have noticed the Similar Topic or Related Topic feature.
Anyhow, as this has been raised, we'll just try out a feature that feature again, and this time try and display possibly similar topics as people are posting. It may need to be turned back off again due to the technical effects of it though, but we'll see how it goes.
All the best,
Trystan
