GAH.
Due to a false alarm, I almost thought I missed tutorial registration.
That whole iteration 1 and 2 thing is just too confusing. They should put CELC/ECE tutorial registration under a separate listing to avoid unnecessary panic.
On the up side, I'd actually forgotten about registration in the first place anyway (I've only 2 tutorials so I've been more concerned with settling the LKY SPP module/ISM), so I won't forget it this time.
