A new batch of emails was sent out today! So far three other guildies has gotten their Welcome emails this week. Also, I don't think we're allowed to post screenshots of Pottermore, otherwise I'd be taking loads of screens and posting them here. However, this was posted on the official Pottermore blog, so it's safe to post it here.
Spoiler for Pottermore Potion Making:
This shows a bit of how potions are brewed in Pottermore. After you've followed the recipe, you wave your wand to start brewing the potion. However, if you didn't follow the recipe precisely, the cauldron starts fuming green smoke, and you
may be awarded one house point. There's a chance, however, that your cauldron may explode if you don't follow the recipe precisely. Not only will you need to purchase a new cauldron, but you'll also lose five house points. Follow the recipe correctly and you'll earn five house points.
