it may be a good idea to email to all the people who particiapted in a thread whenever a 'reply' is aded - much the same as facebok does it. it is nice to receive an 'interupt' rather then pulling the thread every few minutes
Hmmm, thats an idea but I can only imagine that you'll be getting a lot of emails. I don't think you realize the amount of spam posting we get on the forum.
