I recently submitted a game request for Warlords 2: Rise of Demons, a flash game I enjoy playing and want to submit runs for and create a section for. However, the response given to me was I should talk to the series moderator for "Warlords". But this game is not related to that series in any way to my knowledge, its a flash game that is a sequel to Warlords: Call to Arms, another flash game. From what I know, these two series have no relation and therefore I hesitate to ask the series moderator to add it. Do I resubmit my game request and specify this more than I did before or do I request the series moderator to add it?

yes, i'd say to resubmit and make this clear.
