More Wikis

After I watched couple of videos about how to use Wikis and visited Manukau Libraries Wiki. Added my favourite numbers, holiday destinations, music and a new page of favourite tasks of Web 2.0 training. I feel like a chief editor. Powerful eh! But somebody may delete my page. But that's exactly the beauty of Wikis. Anybody have the same authority to the websites. When I was doing the editing a question came up my mind: what if more than two people try to edit the same page?
