Last week we announced the beta release of the Mysteries Revised/Mystery Cults datasheets for Metacreator & Ars Magica. Every customer who pre-ordered this was sent an email with the download link. I've noticed that many of these people haven't yet made the download. Perhaps they missed the email, amidst all the spam that plagues us all.
So if you pre-ordered the new Metacreator expansion, it might be worth taking a peek in your spam trap! Peggy also says that you can contact her directly at email@example.com for a download reauthorization, if necessary.
