Thank you for the speedy fix Bob.
As a workaround I wrote a PHP script that would allow me to subscribe new users automatically, which is useful because I actually only want new users who have also purchased a subscription (user roles Subscriber & Customer). As a development request, could you add the option to choose which user roles are automatically added to Arigato using the “Automatically subscribe to the mailing list all new users who register in my blog.” option?
Thank you for your response. I have tested this and it doesn’t happen when the user logs in for the first time either.
