Although, I just used this as an example to bring up a suggestion about how our local board should be like, so that we people will make decisions about how our local board should be like, it was really good we had good discussion about this and I was surprised people were concluding this to be a good suggestion and highly welcomed by Nigerians on this forum that participated in the discussion.

Child-board for politics and society was suggested but some people still think that it is not yet necessary.
Also to make the main board '(Pidgin) Nigeria' was suggested but another user commented that Pidgin is not only spoken in Nigeria, it is also a lingua Franca in some other west African countries while native languages might still also fit into the local board later, which means all Nigerian languages are welcomed.

In accordance to our discussion, this were what we wanted for our local board:

Main board
Nigeria

Child-boards
Altcoins
Marketplace
Off-topic

I will be making the introduction of this on our request board and edit the OP. If there is anything anyone of us is not yet pleased with, let us know. To add more board, we can still later request for that as once suggest, or if we have local moderator, that would also still be easy to achieve.
