The number one complaint among our users is that the "Follow This Topic" box is checked by default. We have lots of frequent posters, who find it annoying that they have to uncheck the box every time they post (or, if they forget, receive unwanted emails).
I have instructed these users to turn off their email notifications, but that turns it off globally, and makes it impossible to get email notifications in the special cases when they actually want them.
We would very much like an option in the admin tool for making that box unchecked by default. Thanks.
