Keith,
Yup, we understand the importance of this, and plan to have an email notification feature for new comment posts in version 3.2 of JFBConnect. We're a actively working on that release right now, and are shooting for the end of this month or early next month to get it out. In the meantime, and in addition to what we're doing, you may want to check out Facebook's new Comment Moderation Tool. It's been hit or miss for us so far in testing, but looks like it will be great when some of the kinks are worked out. Check it out below:

We'd love to hear your feedback!
