What happens when people signup for your nation?
There are two ways to do it.
All Nations have a default sign IN with email link which will bring you through this process as a supporter:
Or, you can use a sign UP page and you will go through this process, it ends with the same activation page but you can take it off of the autoresponse and just leave it with a thank you - the email will then be in your database. If they want to make an account later they will be prompted to do so when trying to sign in!
