Commit to a schedule. Start it twice a month, on Wednesdays (just an example). Stick to that schedule, even if there's not enough articles. If you wait for it to fill, it might not happen, or when it does, some of the earlier articles will become outdated. If it comes to a point when twice a month is not enough, start pushing it weekly.
Game is not as active as it used to be, but if you commit to a schedule, it will eventually fill better. I can post regularly, and I know Mentor does too. Other managers will see its back alive and will start posting.
