eHarmony does provide an excellent source of potential matches. However, they do not distinguish between active and inactive members. Inactive members (dead wood) do not communicate. eHarmony suggests that you wait two weeks before closing the match without a response from a request to communicate. You can even send a "Nudge" after one week to let the person know that you are still interested. I have found that if a person is going to respond (yes, no or hold) that in will happen within 72 hours. Give them 3 full days and then kick 'em to the curb - you have selected an inactive member or a careless person. Why doesn't eHarmony identify or delete inactive members? Revenue!
