How do I change my user name here?

Contact Auctiva (file a support case) and they will change it for you.
Send them your current user name and what you would like to change it to.

I forgot to add that if you want to change your user name here on the boards - click on the Go tab - My Space - Profile.
Change all the fields that have your current name.
