Wikis - too fast?

Something else I have wondered what they were.

In one of the blogs - I found a reference to "working on a project". This made the light bulb go off over my head! This would be great for those "team projects" at work or school when everyone can not get together at the same time. Each person could work when it suited them - making changes - adding - deleting....

But - my problem I am finding is I am a control freak. The thought of anyone making changes - and then the public believing what is there just spells danger to me. I did notice that many of the wikis had messages on them "due to vandals you must now register or log in or....." so there must be more freaks like me out there.
