Phpbb/php experts? or people who may know how to...
 

Basically, I want to *only* display a list of users who have filled in a field. If this person has not filled in this field, I do not want their username displayed on the list.

How can I do this?

anyone ?

phpbb uses a database (usually MySQL) to store information. You need to find the query used to find users, and modify the query so that it checks for the presence of data in the column of the database where that field's data was stored.

Can't really tell you anything more detailed without seeing the code.
