i believe a lot of the duplication of thread happens because members checks for an existing thread before start writing. now, opening posts are usually a bit bigger and takes about 1-3 minutes to write. meanwhile, someone else can check the threads, not find any similar and start writing a new thread. then, when finished writing, both will hit "post new topic". and the result is duplicate thread. i know this because it actually happened to me.
question is how to fix it? one way could be to open another browser window and check before hitting the button. but that would be really inconvinient.
you have any suggestion?
