Hi,
The forum runs on a platform called jive and at least once a year it gets a complete overhaul, which tends to break basic functionality, eliminates useful functionality and add new cryptic features with fluffy marketing terms I don't understand...
I used to know what it all meant, but I lost track and just gave up trying to understand it all.
When I saw the list.. I wasn't sure which one is it as inbox isn't email and Email watches wasn't convincing but might be the one, but I do know that it is that list of settings that takes care of it.
FWIW, what Jive calls "inbox" (that I __never_ever__ use) is under the "activity" link at the top.
I looked at it and it is unusable for me, but I use the forum a bit more intense as most users.
PS: Strange that you also have a "moderation" option as you're not a moderator
