[PEAK] Wiki lockdown begun

[Phillip J. Eby]

FYI, I've disabled editing of the Wiki by unregistered users, to keep from 
drowning in spam.  The spammers were mostly sticking to off-the-beaten-path 
pages, either replacing them entirely or tacking links at the end.  But 
recently they started randomly replacing snippets of pages with real 
content, which was much harder to clean up than their older tactics, and 
besides, the RecentChanges list was filling up with me removing spam from 
pages.

So, if you want to edit a page, be sure to sign in: just click on 
UserPreferences if you see it in the upper right corner of a page (instead 
of your name, which means you're signed in).

I don't know if this will be enough to stop the spammers; if they stop to 
read long enough they might figure out how to log in, but since most of 
them don't even bother to uncheck the "send e-mail" checkbox, I'm guessing 
most of them aren't paying close enough attention for that.  :)
