You could also use a different approach;
If you click on your members name, a page will open and above your name, you will see the box "modify profile".
If you put your cursos on it you can choose between several options; one of them being "notifications & emails".
If you click on it there are again several options to choose from like "turn notification on when you post or reply to a topic".
This way it will do it automatically every time you post or reply.
