Thanks for the very quick response! I am trying to subscribe to the sub-forum, so that every day i get an email detailing which threads within that sub forum have new activity (new posts). Thought such a function would be very useful. At the moment, if I hit notify in the subforum, I only get an email when a new thread is created. If I hit notify in every threads, then I will get tens of email notification associated to all of the threads, instead of just one summary email. Being new, I am interested in all threads within the sub forum to improve my knowledge. The same trick has been proved to be very useful for me over at FT for a while now.
(not trying to demand any thing btw, just thought I should ask if anyone know how to do that)
