id242, you don't recieve emails for replies to post reminders. They are there as, basically, bookmarks.
Flint does not want to receive all posts in one of his forums. He doesn't even want to recieve all reply's in the thread. He just wants to recieve replys to his post. Specifically his post, so that he can reply to every response to him, without having to wad through hundreds of posts to look for a response.
