'Comments' configuration

Hi,

I have an install of Gallery (just upgraded to 1.4.4-pl4) and have the comments features enabled, however it's not the way I'd like it. I'm not sure if this is possible or not...

I have all users using one login so I'd like the comments feature to be set up so the person has a blank where they enter their name, then a blank for their comments. Is this possible? What is the setting I change to do this? Right now it's showing:

Add your comment
Commenter: username-used-by-everyone
Message:

Thanks!
