Maybe I overlooked it on your site, but I didn't see any scheduled courses. Do you have any upcoming renewal classes scheduled?
I don't list dates on the site -- because my classes usually fill up within an hour or two after I announce the date. So I hate to have people read the date online, start planning with their friends, and then learn that the class is already full.
Plus, not everyone qualifies. I usually have folks call, or we exchange emails, and confirm that the class is a good "fit" for them.
