Hi frazor,
I’ve updated the old b2 evolution import script to work with the new wordpress 2.7. I’ve tested it against a b2evo 1.10 installation and it works without any major flaw.
You can download it on github: http://gist.github.com/102499
Please note that I’ve added some DELETE statements that delete all categories, posts, and comments upon importing: if you already have some data in your WP installation, you’d better either start off from a new one, or comment the DELETE statements in the code.
Have fun! 🙂
