Hi and thank you for your time.
What do you mean by "account". Are you referring to an API request to transmit data to their server?
On another note
My application has an email preferences tab (although it is in development and hidden, damn mail triggers!). The system will issue a reminder email when something needs to be completed (such as vote on some evidence, or a reminder that evidence needs to be submitted). These activities are fundamentally linked to the mechanics of the system (or think game), and contribute towards its useability, and enjoyment. They are also highly requested by our users.
In short, I'd like to set this "on" as default. The email would be issued only where the user has taken some direct interaction with the web app. Is there a problem with this? Of course the user could go directly from that email to their preferences to alter the settings. I am not 100% set on this, and as I have said, I want respect for our users to be the guiding factor. In this case, I believe they would add enough value to perhaps justify their inclusion.
