Hi Emily,
I don't have specific information on classes but I think this will tell you how to find out. It's from the class page on the Radiant Recovery site:

"To see a listing of the next start dates for classes, click here. Please wait to sign up for a class until a week or two before the class is scheduled.

Shortly after you register and before a class begins, you will receive an autoresponder or an 'invite' to join the Yahoo email group through which the class is being conducted. Please be sure to click on the link in the email to join the group. If you do not receive an email with a link to join the Yahoo group, you might want to check your spam folders to see if it fell in there.

We also ask you to read our Yahoo for Smarties tutorial which explains how email lists work and what our Rules for the Road are in terms of participation so that everyone feels safe in sharing.

If you have further questions, please check our Question and Answer page http://www.radiantrecovery.com//classquestions.htm or email me at kathleen@radiantrecovery.com."

In this case you might first want to check your spam folder if you havea spam filter, or if it's not there, you might want to write the email address.
