One feature from seqanswers that I like very much is that once you type in a title, you're immediately provided with an automatically generated list of similar posts. Of course, one could say that it is the asker's responsibility to search the site for whether the question has been asked previously, but the reality is that duplicate posts do still occur. I think that this kind of feature would contribute to greatly reducing the number of these on this forum as well. Would this kind of feature be possible to implement in Biostar? I do see that each post does contain a "Similar posts" button, but I've only ever gotten the result "Search error: list index out of range" whenever I've tried clicking on it - not to mention that such a button only appears after I've posted my question.
