This too is a good point. Although if there is a problem post(swearing, spamming etc.) or you want a thread in your league forum stickied you could contact a MOD. Thats what we live for! We dont have much else to do ;)
you are most likely a global GM, Since when i was GM, i needed to ask to add every forum i like to moderate. So i needed to redirect moderation request from league forum, to a gm ;)
Don't know if they changed it today, but this would be more a reason against it. Even when i think that you can make a mod page.
