I have sent two waves of emails to the beta and gamma purchasers of HARP SciFi in order to check that the email they used when buying the relevant edition would be appropriate for sending an OBS coupon. Some of those emails have already reported Delivery failures. I will be making a list of the real names associated with those emails - if you are on the list, send me an email at director @ guildcompanion.com with your new email address. To prove your identity, please also indicate your old email address and/or your real-world physical address at the time of purchase.
Best wishes,
Nicholas
