There is a change to my personal preferences on the web-site.
I never got emailed about new posts in a thread I started or contributed to until a [EDIT] couple of [[/EDIT] days ago, but now I do. I can promise you I never made that change in my user-account level preferences as I haven't messed with the control panel in years; I've had no need to, the site worked well for me as configured for donkey's years.
Do you want me to change that setting which if I remember correctly is at the user-account level control-panel? There may also be one at the forum or thread level but to the best of my recollection I've never messed with those, if they exist.
Do you need my permission to fiddle with those? If you do you and your tech support people have it.
