The ethic behind the phpBB design apparently is based on the idea of no-spam. Forum user should have the ultimate say on what topic or forum he or she would like to subscribe, which most of us with common senses would have agreed. However, with my observation of the behavior of today's web surfers, there are quite few of them are lived in a very fast pest live and would not pay much attention to a lot of messages like: The user agreement, The user guide, or any community rules.
Rules and laws of a community all work around human behaviors. The design of computer software and social media should also work around human behavior. As long as the citizen and the forum user have the ultimate control, the system did not violate their right. In the case of the phpBB, the user does have some kind of ultimate control by routing forum notices to their junk mail box even though that really isn't an appropriate solution.
With regarding to the previous discussion, personally, I believe phpBB could made the following changes:
- Allow users to remove themselves from the forum and delete their email information from the system.
- An option for user to explicitly disable the forum to send email to them.
- Give administrator the right to set forum subscription settings.
- Allow administrators to force one forum subscription.
Having the discussion out of the way, here is a way to set forum subscriptions to users by forum administrator by adding entries into the database table. The table that controls the forum subscription is forum_watch. By adding entries to that table, you force the user to subscribe to a forum.
The user_id is stored in the user table and the forum_id is stored in the forum table.
