There's no need to remove the original question and ask for a thread to be deleted once you get an answer. The purpose of the forum is to provide help to others, so if you leave the question in place someone else with the same problem can find it and the solution. Whereas if you remove the question and ask for the thread to be deleted anyone else who has the problem in future has to ask again (and, if the right person doesn't see it, maybe not get an answer).
