I have activated Akismet. I have deactivated the math problems for now, to see how well Akismet works. It may be back.

Unfortunately, the most successful of the math plugins was the original one, which suddenly stopped working at some point but then started working again. I fear that if I go back to that one, it will stop working again.

Just a reminder, but my offer to give regular users an account still stands. A benefit of having it is being able to post if I put in a captcha that doesn’t work. And the ability to edit your own comments.
