Then you say well, you can just merge those threads but then we have to do what the member should have done in the first place and search. And we'd have to do that with every "new" topic to make sure that this hasn't already been discussed.
We have 70K members now and only so many mods available during certain times. We have plenty to keep us busy as it is right now. And we don't want 50 threads on the same subject because then the members get sick of seeing it and start complaining, which also leads to flaming. I just don't see it as a doable idea.
I do think that it was a mistake to merge Sals thread, but hey, we're human you know? As I said we do take into consideration if the thread is unique. We don't want to just dump that into the 2.2 thread, we would like to see conversation on those.
Just giving you my point of view. Hope I explained it well.
