Sure… If I am understanding correctly.
Deactivate the Link extension, it’s not needed for your use case. You then need to enable the “Submit New Entry” option. for Form. If you enabled the require login to view the directory, you’ll need to disable it so site visitors can see the directory, but set all your entries to private.
Users will still need to be logged in to view the directory contents but anyone will be able to submit info to the directory, moderated.
Is that, that you are trying to accomplish?
