hello

you change your mood at the top right of the page under where it says "Welcome timeless" There is a drop down menu there with moods to select from

your signature and avatar are added via the left side menu in your user CP http://neurotalk.psychcentral.com/usercp.php

I noticed that you have NOT yet added an avatar, so that is why it does not show.

you added a profile picture, but no avatar yet

hope that helps

welcome to NeuroTalk
