E-Mail subscriptions
Forgot to mention yesterday, but one of the new plugins I installed yesterday allows you to subscribe to email notifications of new comments. Of course in most cases RSS is better, but if for some reason you are unable to use RSS (e.g. you are using the standard Windows infliction of Internet Explorer and Lookout Distress, neither of which have an RSS capability) email is alright (I say alright because afaik you don’t actually get sent the comment, you get sent a link to the post which you have to open).
