In an effort to decrease duplicate content I have added a new Addon: Similar Threads. This addon shows similar threads when posting a new thread(below title) and when viewing an existing thread(below quick reply). It searches only in the title of the thread for similar words so it is important that everybody respects the posting guidelines(to have threads with proper written titles, besides others). The maximum number of results displayed is set to 6 results. Demo: Hopefully you will find this useful.
