The only dumb question is the one you didn't ask
Yes, you are down for section 1. If you look at the Magic Window (the box in the first post) you will see your name alongside section 1 and the date you claimed (you get 2 months from that date to submit a file).
If you click on your name, you will see your personal catalog page, which will list your sections and their status. You can share this with Great Aunt Maud so you get kudos; you can also keep track of what you have signed up for... it's not unheard for us to get a bit carried away and claim a whole bunch of sections, then forget what we've done (yes, that's the voice of experience )
