I have a large group of members stored in a .csv file; these members have custom fields.
I would like you to write a script that
1) adds these custom fields to an existing IPB 3 forum;
2) adds the new members to this forum;
3) adds the values for each member's custom fields to the forum.
Note that the IPB forum already has members in it, and some of the members in the .csv are already inside the IPB forum; you'll have to test by email address.
The .csv members' passwords are stored in md5.
I look forward to your proposal.
