Welcome to the Bitcointalk community!
I just noticed from the country listed above only South-Africa is allowed, and I am not seeing Nigeria being included in the list. I want to know if your project had no planned to allow and permit people from Nigeria to gamble in this casino?
If yes I would want to know your decision for not chosen Nigeria, as i believed that we have wider audience from gamblers in Nigeria which I think would also bring benefits to Nitrowinner.com. Please think about this and includes Nigeria to the list.

Anyway if you looking for a community manager I would refer you to contact AB De Royse777 and here is his service thread you can look up to him on the management aspects and how often he has been on the space managing serious of projects, have a wider look at the services or inboxed him on telegram @Royse777.
