Can I suggest that you include the "number of views" in the forum as part of the criteria to raise a problem. I have just learned that if you post a problem and it gets a lot of "me too" responses it goes down in importance. To flag it as a bigger problem everyone has to create a new post. This may not be under the same or a similar name!
I think that if hundreds of people are looking at similar problems this would be a better warning flag.
Either that or add a button at the bottom of the post, beside "reply" that people can use to report the same problem with the same title.
