How do I change my profile name on yiiframework.com

I just created my first extension and it shows my username as my email address. I do not want that. I’ve changed my name here in the forums to polyhedron, but for some reason when I leave a comment or create an extension it show my email address. How do I change this.

and

Change Avtar for that

Thanks. I tried that (now 3 times) and it still shows up with my whole email address. It shows the correct display name here in forum, but the extension shows my email address.
