Free PHP Scripts by Gscripts.net

This module is intended to supply drupal sites with an easy, non-intrusive mechanism for allowing visitors or registered users to suggest links to other sites.

You have the choice of having suggested links "auto-approved" i.e. approved without administrator intervention or (by default) look at the list of links and approve those that have been suggested.

There is also basic functionality for reporting broken links.

Please note that this module has only been tested under Drupal 4.7.2.

NOTE:
My appologies for the time it is taking to get to the issues on Easylinks. This is due to a family crisis.
