Hmmmm... I receive an e-mail every time somebody comments on something I wrote, comes from a custom e-mail specific to the user. Example: I was notified that you had commented here with an email from "sasjhwa - LJ Comment" with whatever the subject line from the conversation is. Body of the mail is MY comment followed by YOUR comment, and a handy text box for me to reply directly from the email with. I'll find the setting when I get home for ya ;)
