Yes, I can find it. The point of mentioning the second part is that the URL in the automated emails should be correct. (... or the URL it gives should be redirected to the real one.)

As to the deluge, no, it's still happening. 5 emails in 2.5 hours for the same watch.

The way most web-based boards I've seen work for non-digest to send a limited number (usually one) of emails until the user visits the thread, or at least to offer that option. If we switch to digest, then emails will be sent way too late to be worthwhile receiving at all in some groups (e.g. beta test), but set to non-digest means a flood.

Also, it's even worse than the worst-case should be. One extra email is sent per thread, so if the number of posts in a new thread is n, the number of emails received is n+1. e.g. I have a category watch on beta testing. There's a new (and completely off-topic) thread called "AMD Mantle VS Microsoft Direct X12" in beta test support. It currently has 3 messages. I received 4 notification emails, the first two being 33 secs apart.

This is a perfect example of why many sites implement a limit on non-digest emails on a single topic. When you see a notification for something off-topic, you shouldn't have to turn off a whole category of notifications in order to not get spammed by more of them.
