established forum culture / member "policing"...?

Hello all!

I’ve been reminding a few people to mark their posts with [SOLVED] when they are so, and I’ve observed a few others doing the same…

-But the more I do it, the more I hear this forum-post generating itself…

Is that, or should that be, established culture, OR is it just a minority opinion? -And if we agree its a good idea to add [SOLVED] where applicable, should we remind each other to do so? I don’t want to be “that guy” if nobody really cares…
