    in general it is vastly preferable that we keep the contents of question statements as self-contained on this website as possible. Therefore I reverted your edit which replaced the above question Text with a Linked Image. Your edits to this question may be interpreted as borderline vandalism, please refrain from that in the future.2011-04-06
