Adding wp users

Hi Peter

I’m converting a bespoke old php app , to wordpress , using WP data access to create the members details , and other membership structures , branches and membership categories

I have a table setup with members and now I want to add all these as WP users , using the member userid that is in my members table to link the members to a WP user ( its normally their email address so will work for wp as well

So I’m doing this the wrong way around than normal , create the wp user and then add membership details. this is just for the initial setup transferring current members to new system as once its done , I will add members using a registration page , so wp user and membership details will be captured at the same time , any ideas to do this would be appreciated
