We changed to a different skin for the Off Topic forum, the only one that allows avatars, and the blue dummy avatars are back. I followed your directions and looked at the contents of the third box, but I don't know what to change them to. Delete everything in that box, or what?

No, add this at the bottom of the third box to rid yourself of the default avatars:

.default-avatar {
display: none;
}
