I’ve updated everything and turned comments back on. As far as I can tell, everything is working correctly. If you have any problems and can’t leave a comment, email me at jcs at the domain of the blog.
While the captcha was disabled, there were several, presumably bogus, user registrations. I’ve deleted all of those but I may have inadvertently deleted a couple of older legitimate registrations as well. If you’re a legitimate user and I deleted you, please accept my apologies. If we ever meet up, I’ll buy you a beer.
Update: except → accept
