From 2005 to 2011, Thomas was a very active member of the international Harry Potter fan community. To mention some of his major achievements, he was the 'Representative of EmmaWatsonEmpire,' founded 'The Knight Bus' – a Harry Potter link directory – and later the 'DA' – an international website alliance for Harry Potter fan communities which intended to get the fandom to work together. During his time at university, he decided to write about his involvement in the international Harry Potter fandom. According to Thomas, his time being active in the virtual Harry Potter fan community was crucial to his personal development and gave him both, plenty of inspiration as well as the strength to become an author. His first novel was published in 2011. As of 2016, there are four books by Thomas Sailer in existence. Thomas decided to provide the e-book version of CoaHPF for free, to make sure everyone who is interested will have access to it.
