Katherine, they send out the newsletters regularly once you join. They come like clockwork.
Have you made sure that when you joined they have your correct e-mail address?
You would have to unsubscribe, don't think that they would do that.
Anyway you can still read it by going to the home page and scroll down to the very end. If memory serves it is a light blue area. In thre you'll find "newsletters". Click on the week(s) that you would like to read. And double check your membership info to see about the e-mail address.
