Just got done collecting the fuck out of the site. Oh god, I'm so done. I wasn't properly aware of how big the site is until I was hoarding all the pretty images.
I even registered a 2nd time (Heh, got different questions, but got into Hufflepuff again. Aw yeah, I'm such a Hufflepuff!) to get to the wand-selection images and such.

The later books felt short, but didn't know how just short until I collected Moment images! As a fan that makes me sad, but at least as an image hoarder it made my life easier.
I had had expected a Fiendfyre Moment, but no. There was no 19 Years Later either. I'm hoping the new Pottermore keeps the Moments and adds some more to the later books.
