XF 1.1 Change Avatar question


I have a forum.

I have noticed that when I am logged in as the admin, and I hover over my username there IS an option to change the Avatar. However, when I create a new user account and login, and hover over the username, there is NOT an option of "Avatar" for the user to change their avatar from the default. It simply isn't there.?? I've created several new users, and none have the option of changing the Avatar. Am I missing something simple?

Is there a setting in the ACP that I should be changing so users can change their Avatar, or is this a different issue?
