This section allows the administrator to validate links in the directory. The section lists all links in the database, displays their current validation status, and shows the URL of each link for manual verification. 
<h4><li> Continue Validation </h4>
Since link validation is a batch job that takes a long time even on moderate size databases, it is common for administrators to run it in several sessions. The Continue Validation' function allows the administrator to continue the process where it was left off. It also detects new links added to the database since the last session, and adds them to the validation batch. 
<h4><li> New Validation </h4>
This function restarts the entire validation process and resets the validation status on all links. You should use it periodically, for example once a quarter, to ensure that all links in your database remain valid, or when there are major changes in your database. 
<h4><li> Validate </h4>
This function validates a specific link or a selection of links. It is designed for one-time uses, for example, when you want to verify the newly added links without having to wait for the batch process. 
<h4><li> Reset Validation Status </h4>
This function resets validation status on a link or a selection of links. The batch verification will automatically schedule them to be validated again. 
<h4><li> Delete </h4>
This function deletes a link or a selection of links. This is a shortcut for cleaning the database from the invalid, or dead, links. It is the same as the Delete' function in the main Catalog.
