Holly,
Everyone is sent a confirmation - however it may be that Yahoo or whoever your email provider is, categorized it as junk mail. You may want to check that.

You are registered for the class and Gretel says she sent you an email last night. Did you get it?

Two days before the class, you should receive an invitation to join the list for the class. However if your email provider is marking it as junk mail, you might not see it. Again, something for you to look into.

Hope that helps.
Kitty
