I think that I found a few more things that aren't quite right.
I created an event for testing. It shows "added event" correctly, but when I deleted it, it shows as deleting a "repeating event" even though there were no repeats.
When I approve a message on the site, it shows up as approved via email. Membership approvals correctly show via web.
All messages are appearing as "sent via email", even when posted from the site.
