I've got a topic update notification set up. It hasn't been working very well of late, I haven't been getting emails. I suspect it might be because maybe I visit the forums, but don't read my actual thread. Though I'm thinking the fact that I visited makes the topic watch think I don't need to receive an email?

Did you happen to see this? If so, check your spam filters. That has also found to be an issue with delivery.

Nah.. I had it set up before the board version change. It worked fine then. After the version change, I still got a couple, but it seemed like I started missing some every now and then. And now I don't think I've gotten one in a while. I can test some more, maybe subscribe to some toehr threads and see if there is a pattern of sorts.
