title: Return the first letter of each sentence in a string
body: <p>I'm not sure where to start with this one but I'm hoping someone can help.</p>
  
  <p>When a user submits a message I want to check the string and return the first letter of each sentence and place it into an array. Basically I want the first letter in the string and every letter immediately after a full stop (if there are any) placed in an array. </p>
  
  <p>Has anyone ever done this in the past? Is it even possible?</p>
  
  <p>Hoping you can help </p>
