Question about creating a Member List

Hi,

I am relatively new to using Drupal (approx. 6-7 months). I am creating a Drupal site and within the site, I want to create a very basic Member List. The Member List that I would like to create would have all registered users with the formatting appearing as:

Last name, First Name
Last Name, First Name
Last Name, First Name
...and so on

I have read through Drupal Forums and find bits and pieces of what I am trying to accomplish...but no, "Step 1, Step 2, Step 3, etc". I have tried to set it up using the Profile Module and the User List. I now want to customize the layout of the individual profile layout and also the User List. Right now, my User List appears as:

username <-- the username hyperlinks back to the profile
First Name
Last Name

username
First Name
Last Name

I would rather not display the username and just have the Last Name, First Name contain the hyperlink back to the individual profile.

I've tried using Views, but I wasn't able to get it to work that way either. Anyone have any ideas? I used the "Pushbutton" theme and renamed it for my project before I began adjusting colors, layout, etc. The Drupal version is 5.15.

Thanks for any input that anyone is able to provide.

Michael
