title: How can I send an auto-generated email every x-days with php mail(), without access to cron?
body: <p>I am trying to send an email, via php's mail function to user's every 15 days to remind them of a particular item (no worries, nothing spam related).  I unfortunately do not have access to cron, so I think I would need some sort of client side solution (is this correct?).</p>
  
  <p>A link to get me started or a general outline of what I need to do would be great.</p>
  
  <p>Thanks!</p>
