Topic: Avatars and Password Changing
Admins and mods can upload avatars for users that don't yet exist by changing the id in the upload_avatar URL. Not really a big bug, just something worth noting.
Another thing like that is that on the profile screen, the Change Password link always appears if you're a mod. However, you get Permission Denied if you click the link on the profile of a mod or admin. The link should probably be hidden in that case
