We all know that Nigeria has English as the official language but Pidgin is spoken almost everywhere also. Which means English and Pidgin are spoken almost everywhere in Nigeria which makes that his posts to be a lie. We have discussed about this in the past. Most people like freedom to post in both languages.
I don't think boards should be mandated to use language. Although our mother tongue is Pidgin, writing in English seems easier to us. In Nigeria, English is given more priority in official work, which has a noticeable effect when we go to a government office for a job, even in education. It should be reasonable to keep the use of both languages as universal which can be easily understood and express our opinions more easily.
