I recently submitted a module for the Ancient Wars Series submission, having created a page for it. I haven't heard a response yet I've seen other modules get published in the meantime. This is the first time I've submitted a module; I have an update for the Strike of the Eagle module I'd like to post but not until I hear about the first submission.
One concern I have is that the series was original a set of four S&T magazine games. Subsequently, the rights were sold to Excalibre games base on what I learned from Doc Cummins at Decision Games. As such, DG won't publish the vassal module as it's not their game anymore.
