Changing profile URL

I noticed while testing elgg that it creates the profile URL's  example.com/profile/myUserName
I would like to know if it is possible to change the URL to example.com/myUserName

It makes it much more useful in the real world for a user to say "Find us on example.com/myUserName" than to say "Find us on example.com/profile/myUserName.

Other than make it easier for people to Market their product pages on your website, it also can drive traffic by marketing the fact that users should sign up immediately to reserve their preferred user name because myUserName is better than myUserName_1

 I have not launched my site yet but the URL thing is fairly important to me.

Thanks.
