Jay said: I received topic update e-mails Friday, but none since then. I made a change to the database on Saturday that I think might be the culprit.
That sounds about right for me too. I'm glad I'm not alone, to be honest. Even YOU aren't getting them. That seems even weirder!
This sort of thing happened to me on another forum, but got resolved after some tweaking. I'm sure it'll be fixed in time here, too. :)
