title: Regex to find all words that start with @ but ignore email addresses
body: <p>I created this regex to match all words that start with "@" in my string, there could be something before the @ tokens as well. it works well but it also catches email addresses and i would like to fix that.</p>
  
  <pre><code>(?&lt;=@)\w+\b
  </code></pre>
  
  <p>Example string would be:</p>
  
  <blockquote>
    <p>hello @bob, how are you? @mark, @emma and @chief are with me. email me
    at test@email.com!</p>
  </blockquote>
  
  <p>Can you help?</p>
