I’ve switched from b2evolution to WordPress for the software that runs this blog.
I had been planning to do this for several weeks because b2evolution was too spam-friendly, and WordPress seems to have a competent approach to comment spam (holding comments for moderation if they don’t come from someone who previously made an approved comment). I was forced to shut down the b2evolution software yesterday when the load it put on my system became excessive.
I think I’ve fixed all the permalinks to work as before.
