So I asked this question recently, and then figured out what was wrong myself after an hour or so of investigation. Nobody else had put the correct solution down, so being a thoughtful chap I posted my answer and put an update in the question. Being that there wwere no other upvoted answer and that I'm not able to mark my question as accepted for a couple of days I decided that I'd also put [SOLVED] in the title to show to anyone looking through the list of unanswered questions that its been solved.
Now clearly I've broken some sort of unwritten rule here, because someone has downvoted it - apparently because of the [SOLVED] in the question.
Never mind that the question is well written, correctly tagged, and that its even a pretty reasonable question - none of that is worthy of an upvote, but trying to be helpful and putting [SOLVED] in the title is worth of a downvote...
The best bit is that whoever downvoted the question was quite probably perfectly capable of editing the title themselves anyway, but they chose to downvote it instead...
Gah! (</rant>

Anyway - so I take it there is a taboo against putting [SOLVED] in the title of a question?
