When I reply to a thread to which I am already subscribed (email reminder), it should remember that I am subscribed and check the appropriate check box on the reply form.
It currently works such that if I subscribe to a thread once, then reply and forget to check the box, it erases my subscription to the thread. Otherwords, I have to click the subscribe box every time I reply.
It's there some sort of sql call you can add it to remember that I'm already subscribed?
