A time-saving hint: when reverting due to vandalism, find the last good copy on the history tab (e.g. "14:09, 12 February 2007 Anville"), click on it (http://en.wikipedia.org/w/index.php?title=Richard_Dawkins&oldid=107636702) and then press the edit tab on the old page. It will warn you:
You are editing a prior version of this page. If you save it, any changes made since this version will be removed.
But that's what you want :) Just scroll down and press Save Page and the entry will be good as new! -- Limulus 03:41, 14 February 2007 (UTC)
