Topic: [Extension] Subscribe to Board
For my own needs, I have written a small extension that adds a profile setting to subscribe to the whole board. If the setting is enabled, an e-mail notification is sent to the user on every new post that the user has permission to read, on the whole forum. The e-mail contains a link to the “New posts” menu. Until the user clicks the link or visits the forum in any other way, no further notifications are sent. This way, the number of e-mails is kept low for people who do not read their e-mails too often, but still they don’t miss a posting.
The extension is developed on https://gitorious.org/cdauth_punbb/subscribe_to_board.
