Thanks to Shaggy (thanks Shaggy!) I got my Private Messages working. Then I installed the Private Message Notification MOD. It's working, however when the pop-up (?) comes up on the lower right of my screen telling me I have a new private message, it's got a broken image (the box with red x) in the upper left corner of it. The instructions say to put the icons in my "images" folder, however I never established an images folder. I tried putting the icons in the root of my forum folder, that didn't work, so I created an "images" folder, and it still isn't showing.
