For a while now, we've had How can I take long exposures using a Nikon D7000 with wireless remote?, which has an accepted answer so I'm assuming working for the original poster. Today, a new user posted How can I take long exposures on Nikon D7000 with a wireless remote? (I edited the question a bit; you may want to read the history to see the original version) noting that he'd tried the stuff in the original question but it didn't work for him.
The new question now has some close votes marking it as a duplicate of the older question, which doesn't seem to me like it's going to help the new poster much - he's already done the right thing and read the original question, and I don't think he can necessarily edit the original question or the answers in any way which doesn't significantly change the meaning, so what should he be doing?
