The FA has updated its website, with an extensive amount of information regarding Sin Bins. They have also launched an interactive online portal for players, club officials and match officials designed to educate participants on the sin bins process ahead of the new season.
I would encourage you to share this with your clubs. It can be found via our website: http://www.hertfordshirefa.com/news/2019/jul/30/sin-bins and within our social media channels.
Even more information is also available here: http://www.thefa.com/get-involved/respect/sin-bins
