How do I Add a Custom Field to the Prune/Move User Option?

[David Copeland]

In the Prune/Move Option (Under Users), I can choose to FIND all members of a User Group prior to selecting which other User Group I want to move them to, and then click FIND.

When the results come up, I see the following default fields:

Userid

User Name

Email

Post Count

Last Activity

Join Date

-----

I need to ADD to the above list a Custom Profile item titled ExpDate.

That way I can UNCHECK all of the current User Groups, and then go down the results page and place a check on the User Names that have an expired month and year in the custom ExpDate

Where would I go to locate the item (template?) that I can add this to?

And what exactly to I edit to make ExpDate show up?

Thanks,

David

Anyone?
