There is a bug in the nightly notificatons, in that it attaches the wrong message information, when it is referencing a forum that has archives (only 300 active threads are allowed per forum, so the Wiz 7 & 8 forums meet this criteria).
So, though it shows you (Lady Adrexia) posted a message yesterday, it really pulled that information from last June. So, someone did post yesterday in the Wiz 8 forum, but beyond that, the "information" in the subscription is questionable at best.
(*kicking myself*) I did not realize the extent of this problem/bug and should have addressed it long ago. This weekend, the new forum software will be installed and that will take care of that problem.
Sorry for the confusion.
