Thanks for your prompt responses.
I suggest the written articles column is not much used for end users. Usually they do not have the access, knowledge or interest to write any article for a site.
In the short team, the ability of display name, username, email address like the fields in the joomla back-end User Manager will be helpful.
In the longer term, it will be good and flexible if any fields related to the cas_users table can be selected for displayed.
I like the Registered at and Last login at fields.
Great work! Easy to used.
