Anonymous comments enabled

I enabled the "anonymous comments" feature, hopefully that will solve the problems some of you are seeing posting comments.  Thank you Max for pointing this out to me.

(I remember disabling that option when I set up the blog, I guess my security instincts got me to overreact this time...  When we think about security issues, any issue that can be exploited anonymously is way more scary than issues that require you to authenticate before you hack.  After all, there's a limited number of people who can log into my network -- but a near infinite number of people who can't authenticate.  So one of the rules in Windows is when in doubt restrict it to authenticated users only.)
