I'm sorry if this has been asked before; but I didn't find it after a search.

When I subscribe to threads, I select "intantly, using e-mail". But when I get an e-mail alerting me of a post, there is a message on the bottom that says "There may also be other replies, but you will not receive any more notifications until you visit the forum again."

Is there any way to set the thread subscribtion so that I receive an e-mail for every post that comes in since my last visit?
