I currently allow board wide subscriptions but am re-thinking that option. I figure I should get rid of it while my board is young and very few people are actually using the subscription function.
Can I turn the subscription function off but maintain a board-wide subscription for me - the Admin? How can I do this?
You could change the highest level of subscriptions to "forum" and then subscribe the admin to all forums (that's what I've done on my site). If you don't want the members to use subscriptions you could add some validation around the codes for the links and icons that they use to subscribe, but I'm not sure that's worth the hassle.
What if you subscribe admin to the whole board, and then remove the link from the code?
Obviously if members are already using the board wide subscription you will need to find a way of removing them - possibly the quickest way would be to edit the database, although i wouldn't know off hand where this would be in the database.
You could always rely on the fact that when your board gets busy, it is likely that anybody with board wide subscriptions will want to remove it!
