We have an existing PHP script that will check a site's Google PR as well as Alexa PR. We would also like the system to check the following items (if the check boxes are checked): -Sites Linking In (Google) -Sites Linking In (Yahoo) -Sites Linking In (Bing) -Sites Linking In (Alexa) Once the results are obtained, the user should be able to save their search results by entering in their email address and their password twice (one for confirmation). Then you need to build a cron that runs once per week that re-runs the saved query and saves the data to the database. If any of the data has changed from the last time it was run, it should email the user with the value that has changed. For example if the Google PR goes from a 2 to a 3, it should notify the user that it was a 2 and is now a 3 by email.
