looks like o.p is still paying users, it wouldn't hurt to make 10 posts and get out of there i guess ( are you paying for more than 10 posts too o.p ? like signature campaign here)
At the moment it seems he want his forum to start and take off. The more content the better. I bet he will select the best posters and offer them a role as moderator.
The more the forum grows, the more time it will consume.
