I created my first production Drupal website in Summer 2008. For various reasons I'm not a big fan of PHP so I dreaded the thought at first. It took some time to get accustomed to the Drupal way but it was already really easy to set up basic websites.
In the course of 2009 I've created many more websites and I started.
Right in the beginning I tried contributing back to the project but the structure of drupal.org wasn't very clear to me yet. In early 2010 I got excited again about giving back some code and more ideas.
