title: Can somebody recommend a good gem for contact handling?
body: <p>I want to store person / company contacts with addresses and relations. Addresses can have multiple lines for streets, phonenumbers and emails. Would be also nice to have some kind of export feature.</p>
  
  <p>Contacthandling seems like a common task, so i want to know how others are doing this job. </p>
  
  <p>I had a look at the following gems and applications:</p>
  
  <ul>

  <li><p><a href="https://github.com/midas/addressable_record" rel="noreferrer">https://github.com/midas/addressable_record</a> </p>
  
  <p>Encapsulates the composed of pattern for addresses into any easy to use library</p></li>
  <li><p><a href="https://github.com/huerlisi/has_vcards" rel="noreferrer">https://github.com/huerlisi/has_vcards</a> </p>

  </ul>
  
  <p>Are you using one of the mentioned gems, can you recommend other gems or do you implement this on your own (why and how)?</p>
