Plugin for integrating Pushover notifications.
This allows notifications to be sent over Pushover, which grants push-notification support for iOS, through the 3rd party app.
Once installed, you will need an Application API token. Create a New Application and fill out the form.
After you created the application, copy the resulting API token to the Discourse admin plugin pages, and enable the plguin.
All users will then be able to add their User keys in their preference → Notifications.
There will be an immediate pushover message confirming the subscription.
