I’ve got the same issue… several hundred existing WP User/Members that I want to put into Connections directory. Here is what I’m thinking for a workaround. I’m wondering if it will work before I put it out to the users:
Use the CSV importer extension and import all members and their contact information. Then ask them to log in and update their profiles for missing information and to handle any errors that may have occurred to the categorization (ie office phone listed as home phone, etc) If I’m understanding correctly Link should connect them upon log in with the imported information for their entry. Will that work?
If not, my second choice would be to send members a link to the editor and ask them to login and update. I’m just not sure everyone would be diligent about completing that task and I would have a less than complete directory for the membership.
PS I’m integrating with Wishlist member if that enters into your response.
