Is it possible for you to provide me with a list of diaries I am on the notify list of before the change? I'm on lists of folks who hardly ever update. I'm afraid I'll forget to add myself to them without a reminder.
Unfortunately, that's one of the biggest reasons for the change - it's not possible to get a sensible list of all the diaries you might be setup to receive notifications from because the backend data is too 'denormalized'. I could go into a lengthy explanation, but the short answer is that it's unlikely you'd get a meangingful list, unless you've always used exactly the same email address.
If you have always used the same email address drop me a line and I'll see what I can do, but don't expect too much :)
Steve.
