Today I came across a bug that had been reported six separate times. The rankings of the cases varied from in the hundreds to the thousands. Needless to say, not a case that was likely to get any attention anytime soon. I went ahead and merged the six cases. Now the merged case has a ranking in the top 20.
This is an important reminder to make sure you search for cases before entering a new one because as the saying goes, "United we stand, divided we fall."
