UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Customize User List

I want to add a sortable column from the user profile record.

It is the ubbt_USER_PROFILE.USER_EXTRA_FIELD_1 field.

I've had users enter their Graduation year and I'd like to include it on the User List page.

I see that you can modify the showmembers.tpl template. But, it is unclear to me where to begin.

Thanks
