I don't think boards should be mandated to use language. Although our mother tongue is Pidgin, writing in English seems easier to us...
This my post is off-topic but I think it is worth correcting this. Pidgin is not our mothers' tongue. Mother's languages are local languages. Pidgin is derived from English and native languages in a way people that are not educated can also easily be able to speak and write English which led to Pidgin.
