We try to add as many as we can.  We weed out exact duplicates and often even near duplicates (one ingredient different or something minor).  We also do not add recipes that clearly have something wrong with them, are missing major ingredients/directions, or that our editors just cannot understand.  At this time, we also do not add recipes that are submitted with metric measurements as we do not have time for our editorial staff to spend on converting them.  We get thousands and thousands of submissions!
