What does it mean if you're at 5+ hours with 5+ posts and still can't post outside of the Newbie section?
You should contact a staff member. In the OP it says the automatic system updates every 10 minutes so you should have already been granted your privileges.
I would suggest moving into an apartment that doesn't charge you for electricity! If this is too drastic you could attempt to run it on solar power, (unlikely.) Or you could use battery power, (rigging it to a car battery would yield interesting results.)
