Being emailled followups

A question about Blogspot seems best posted here! I noticed there had been some comments on other entries. Surely I'm not supposed to poll each article to see if there has been a new comment. I'm sure there was a setting to say to email me all follow-ups to all articles, but a recent search turned up nothing.
Anyway, thanks for the replies!! I want to try out the Actionscript suggestions I received and will then update the articles if they work (or even if they don't).
