In my recent question I got a lot of answers that gave relevant information, but didn't answer the actual question asked.
I collated the useful information from those answers, made it a community wiki and accepted the answer so that it would be displayed at the top, so it would be useful to those who are interested in the actual answer.
For some reason it isn't displayed at the top, even though it is the accepted answer (it's currently languishing in 14th place out of 15).
Why is this the case? (I'm not sure that it's a bug, but it seemed the most relevant of the required tags)
