Outdenting is tricky on sub-discussions.  My feeling is, that if outdenting is required in a discussion with bullet ponts, you should reindent at least ::.  But it was only 8 deep, which I don't consider too deep.  If it reaches a point where you have to decide whether the discussion is to be at-all readable on narrow monitors, or decipherable on normal or wide monitors, you have to go with the wide.  —   (talk)
