KDE - What's where?

Hi all: I upgraded from 8.0 to 8.2 recently. While I am pretty happy with the upgrade (and the fact that it didn't blow away my /etc configs, or kill off my /home directory), I have had a few odd KDE-related issues with my general-use user account. So much so that I figured it would easier to create a new user and have a fresh start. A quick question: Where are the various KDE-related settings kept? I want to import my Kmail settings and e-mail rules to my new account, as well as my Konqueror settings, etc. I've dug through the /$home/.kde directory, and haven't seen anything that really stands out. Ideas? Tks. Cheers, Todd
