Online mod_rewrite training

I’m considering doing online training on mod_rewrite, based on the book and the training class I’ll be doing next week. I’m still not sure what I should charge, or how I would go about marketing it. But I’ve got Moodle installed, and I’ve got a course outline started. So if you’re interested in taking a mod_rewrite course, let me know, and I’ll try to figure out what I’m going to charge.
