Forum Instant E-Mail Notification for Forums ...?
 

Is there any way I can allow my users the ability to subscribe to a "Forum" with instant e-mail notifications ...? I know this can be done with specific threads, but many of my members want to receive e-mails on new threads within a forum.

I noticed that there were some mods for previous versions of vBulletin, but I didn't see any for vB4.

Thanks!!!
