In today's tutorial, Ishamina Athirah asked her students whether 'creativity' can have a plural: 'creativities'. All her students agreed that the plural noun is fine. This seems, therefore, to be part of Brunei English, and it is consistent with other mass nouns having a plural in Brunei: 'furnitures', 'equipments', 'advices', 'staffs', etc.
I am sure that the majority of speakers of New Englishes around the world would agree with these plurals, and they probably represent the future of English; but users of English in Brunei and elsewhere need to be aware that this is not (yet) standard usage in English.
