Need Help With The Avatars Plugin

Hi, I have installed the avatars plugin as per instructions (on wordpress 3.0)

however in the install instructions it does not tell you whether plugins should be activated via 'network activate' or 'activate' and I have tried both of these but neither show a 'your avatars' menu item in the user menu once activated.

All other precise instructions, folder creations and folder access rights have been set as they should be

Please help
