[PEAK] Wiki defacement; should we lock down?

[Phillip J. Eby]

We had another Wiki defacement today; this one was a script kiddie rather 
than a spammer, who deleted the entire IntroToPeak front page, trying to 
upload some PHP to hack into the machine.

I fixed the damage (AFAICT), but I wonder if perhaps we should move to a 
"registered users only" security policy.  An awful lot of the Wiki editing 
that takes place these days consists of spammers adding links, and us 
taking them back down.  Going registration-only would fix a lot of this, 
but at the cost of losing the ability for people to casually edit and comment.

What do you guys think?
