Yes. Go to the User Control Panel - Board preferences - Edit posting defaults. The last option is "Notify me upon replies by default."never did discover if there was a way to be notified in email if a reply is posted to a post... is there a way to turn that on?
The last line of the options in the same tab panel is "Edit notification options." Here you can choose to get notifications or emails or both.
Finally, make sure you've added an email address in the Profile tab - "Edit account settings."
