Allen,
In 6.1.1 my users could check a box in their profile, just one time, and they would always get email notification of any responses to any posts they made anywhere.
The majority of the people do not want that. Same as you. But I have a few who are threatening revolt if they do not get it back. One of them is a co-owner of the site !!! Yikes !
So, your solution here is exactly what the few want, but it is exactly the opposite of what the majority wants. Everyone was happy with the way it was in 6.1.1...
How can I set things back to the way they were in 6.1.1 ? In other words, if someone checks a box in their profile, it works for ALL of the posts they make, regardless of whether they click the box in the thread when they make the reply or not. And yet those who do not want that feature, are nor stuck with it...
Maybe implement your solution, then have a check box in the profile where people can turn off all notification ??? (Except when they click the box in the thread...) Of course, you'd have to tell me how to do the latter as well. LOL (Using kiddleygarten language.)
