If you're asking, "Do I post asking for permission on the creator's wall or yours?", definitely the creator's; even as the wiki's Bureaucrat, I have no power to authorize you to use someone else's work. If you mean, "If I receive permission from the creator, where should I post to notify the Admins?", just the dialogue on the creator's Message Wall will suffice; Sebolto or I will see it. You only need to bring it to our attention specifically if we revert edits or tag one of your articles with the Links advisory.
