I just enabled authentication for comments on this blog. Hopefully this means I'll be able to avoid most comment spam (the spammers seem to be re-finding this blog after a brief respite when I upgraded my installation). What this means as far as I can tell is that if you register (see link in the comments section), your comment will be published immediately. Otherwise, it'll be held until I approve it and/or put you on my list of trusted commenters.

If you have any difficulties commenting, let me know.
