Hi,
Wouldn't Joomla > Components >
Weblinks
provide what you're looking for?
If you are using the
CB Auto Action
from the Community Builder Incubator forge you would be able to assign your newly-registered users to a 'Submit/Edit Weblink' ACL group which would give you even more permission control.
1. CB users belonging to the Joomla ACL group 'Link Editors' would be able to edit the links.
2. Users belonging to the Joomla ACL group 'Link Submitters' would be able to submit, etc.
Hope it helps
