- Being sorted into Ravenclaw house
- Being able to interact with other people in your house
- Buying potion ingredients at Diagon Alley to make potions
- Managing your money from your vault at Gringotts
- Dueling other people with your customized wand and spells you have learned
And these highlights are simply from the limited content that is being released to the beta testers right now. So far only portions of The Sorcerer's Stone are available so it sounds like there will end up being a plethora of awesome stuff to do within Pottermore. I for one, am very very excited. The site is set to go live sometime in October and registration will be available soon according to Pottermore!
