I am using DNN default newsletter functionality to send newsletter to subscribed users.

My questions are

1.How it interacts with backend database.i Mean if the user has entered one mail id and clicked submit,where this entry in DNN DB will be passed

Because later, say,the admin of the portal will see the list of subscribed mail ids,select them and send the newsletters.

2.Also we get required field validation error when Discussion forum and News letter are on the same page.When users enters Details in Discussion forum and submit,the newsletter throws required field validation error,even though it is separate module
