I have a website that authenticates users with Twitter via OAuth. I need a way to contact users after they registered.
What are my options?
There is no email in OAuth result and “Read/Write/Direct Messages” looks scary. As I understand an OAuth application cannot send a direct message to a user with Read-Only permission.
Is my only option to have users follow me? Is there any way to required that users follow my application as part of the OAuth process?
