The Pottermore Official Insider Blog has recently been updated with some new information for those of you already in the site:
On Monday 15 August, we began sending out Welcome emails to a small number of Beta users. These people have been busy exploring the site, leaving comments to tell us when they like something, and making suggestions when they find something they would like us to improve. We've learned an awful lot and, as a result, have started making changes to improve the Pottermore experience.
Additionally, the official Pottermore twitter account has been updated informing us that they have send out another batch of welcome emails. While some of you have not yet received your email (like many of us at MuggleNet), we ask that you remain patient as we are sure Erroll will eventually locate your home.
