Will I need to reciprocate my listings to other participating CARETS MLS organizations?

When I click the DOM or CDOM links, or run a search from the History Tab, will I get history of the changes to CARETS listings?

Does CARETS have all the MLS data in Southern California?

Will I need to be trained on how to use CARETS?

When will Cumulative Days on Market (CDOM) be displayed on CARETS listings?
