Revert

From CGEU

One of the features of wiki is something called SoftSecurity - it is so easy to revert someones malicious, wrong headed or inexperienced edits, that we don't need to add energy into them, we just revert. An easy way to do that is to go into the history tab above and click on the version of the page before the edit you don't want. Now, edit that page and save it, waaa laaa, you have reverted a bad edit. The tricky part is if there are edits after a bad edit, then you will have to step through each versions differnece (diff) in the history (hist) and figure it out.
