Won't this potentially create a huge amount of emails? What if you have 8000 users and 50 forums. Say 4000 subsribe to an average of 5 forums. That makes 20,000 subscriptions total. Now let's say each of those forums get's an averge of 10 new threads per day. That would generate 200,000 emails! That's alot of server load on an email server along with bandwidth. Even if you half my numbers in the exmaple it's 100,000 emails! This can be a scary one for active boards...
