[Mwiki] New accounts by invitation only?

[tj]

Can I get lazy consensus on requiring users to request Mwiki accounts on 
a ML? Temporarily or permanently, I don't know.

Any Administrator ("sysop") can create a new user account. I will 
research what change is required to block other sign-up methods.

Currently, Mwiki is under massive attack by spammers. Thanks to the 
valiant efforts of volunteers Adailton, Helen russian, Pitonyak, and 
Yak, we are staying even: the lifetime of spam may be a few hours, but 
is usually only a few minutes.

However, the spammers are creating new spam accounts (the pattern in the 
names is quite apparent) at a rate of one every minute or two, and 24/7. 
We cannot survive that kind of onslaught indefinitely.

To be continued.
