I changed my email address about a month ago, and haven't been receiving notifications since. The UCP account settings under the profile tab show the correct address. All the UCP notification preferences are correct.
I'm wondering if we've lost an admin for the forum. I have requested a link to reset my password several times over the past year with no reply. Finally today I figured out what my old password was and was able to log in. I hope you get an answer soon......
Well, I'm baack. After that one success, no new email notifications. I think it might have something to do with how the forum stores subscriptions. At any rate, I'm unsubscribing and resubscribing to a few topics to see what happens. I'll report back if it works.
