Alright, I went away for new years...but now I'm back.

I did this again using an email at a different domain. Still no registration email at the new email address. All moderator emails show up just fine.

The new address did receive the user email telling me that the moderator (me) had declined the request.

From looking at the wordlets, with a moderated request, that new email address should have received the reg_html_mod note first, and then the reg_html_normal when approved?

It seems that none of the reg_html emails are going anywhere.
