I've got .55 installed (works great, instructions were awesome - thanks to the author!), but am having the issue we saw on the last page where there is no option for HTML email at all. All I have under Email Settings are:

Confirm Delivery (Yes/No)
Confirm Read (Yes/No)
Send Read Receipts (Yes/No)

I read something about service books updates. What's the process there?

Thanks!
