I use a lot of answers on this site for various things, but have to trawl about to find them. Could we bookmark answers? Seems like a core element of this site, and Ed: it would bring people back, rather than them cutting and pasting into a word doc on their HDD.
Simply click "Subscribe to question". The question (and subsequent answers) will then appear in your list of "Questions I have Subscribed to" in your profile.
