If you don't know what I'm asking what I mean is when you post a reply you can select the checkbox marked 'Notify me when a reply is posted' and then when someone reply's to a topic you get an email. You can also subscribe by going to the bottom of a topic and there is 'subscribe' link.
I have personally gone into the User Control Panel and found the setting to make the 'notify me' the default when I reply to a topic because if I reply then obviously I care about what is being said
