Report button important fact
Yes, yes, I know there is a thread that KiTFoX made about all the uses, but this is only about the fact that you can report threads to have them closed faster. Most people probably don't even look at that thread in the first place. I keep finding people posting "please close this thread." It just gets slightly annoying since I know they can just report and stuff.
Close if you think is pointless, or sticky if you think it will spread the fact faster.
