Appleford joined the Blues four years ago in December 2014 from Mildenhall Town whilst the club were in the Isthmian Premier Division to assist manager Ben Chenery in player recruitment and development.
Chenery told http://www.burytownfc.co.uk: "I would like to thank Christian for his hard work and commitment over the past four years he has been with the club. He came in during a very difficult time for us on the pitch and gave me great support when I needed it. He has continued to work hard for the club and I would like to wish him all the best with whatever he chooses to do next.
"I will continue to work with the existing management team to deliver our aims this season".
