Below is just a small selection of the Drupal events I've been to. In 2013, 2014 & 2015 I've attended more DrupalCamps and DrupalCons than any other person in the UK.
As you can see below I have attended numerous Drupal events and become part of the UK Drupal community. Meeting fellow Drupal'ers up and down the country has helped me get to know the product and the people behind the projects. I would like to think I have become part of the knowledge base as you never have to go beyond a few minutes of chat before you seem to be able to help people with an aspect of their project.
I have thoroughly enjoyed attending as many drupal events as possible and have presented on topics such as using Panels in Drupal.
Drupal's biggest asset is its community. It is not only friendly and enthusiastic, it is also knowledgeable and dedicated. Easy things to say but true.
