Using the notifications module, a user can edit their own subscription settings by going to the URL /user/[uid]/notifications/subscriptions and unsubscribe from receiving notifications from specific content types. I want to disable the ability of a user from unsubscribing from a certain content type. Would anyone know how to accomplish this either by writing a custom module or by adjusting the configuration settings.
Also, if it helps, I am using the notifications module in conjunction with the organic groups module. So, in every group that a user is subscribed to I want them to be unable to unsubscribe from a certain content type.
Thanks in advance!
