Maybe you're not familiar with the whole Wiki paradigm. It turns nearly 
any network security model on its head since Wiki was apparently 
conceived by a bunch of starry-eyed utopians who believe that all people 
are innately good and only wish to create community and spread knowledge.

I do not need to tell you that this does not work in the real world.

As I indicated, the wide-open Wiki paradigm is silly on the wide-open 
internet. The opposite, the closed-off Wiki is almost as ridiculous, 
except that most people in our group already have accounts. Right now, 
we're investigating better trade-offs.

A huge problem is that MediaWiki is notoriously lacking in access 
control features. Generally, the access modes are either "wide open" or 
"exclusive membership" (and you have to hack PHP code to change modes). 
We're down-rev a few major versions on the MediaWiki software so it is 
entirely possible that they have improved some stuff. If only I had time 
to upgrade. (To further exacerbate the problem, MediaWiki releases a new 
major version ever quarter whether it makes sense or not, and it's all 
documented in -- you guessed it -- Wiki format.)

To review-- the current MediaWiki software that we use allows a 
malicious user to do an extraordinary amount of damage very quickly and 
it is very tedious and time-consuming to repair the damage. That's why 
we had to impose such serious access control, until the situation improves.
