I don't know about Hoss' HTML thing, but you can choose how you want to be notified in your profile.

In the band near the top of this page are a row of links, the second one is "user cp", click that, takes you to your control panel.

Down the left side of the screen are choices you can play with. Click on "edit options".

That screen will have all sorts of things to choose or not. The second box is "messaging and notifications". Within that box the second section deals with "default subscription notices". Theres a drop down menu of choices from "no notification" to a few different ways to get notification....choose the one you like.
