Mandrill, my former e-mail provider, discontinued the service I was using and I botched switching over to a new service. Between 25 and 27 February any attempts by the game or the forums to send e-mails resulted in an Internal Server Error. I didn’t notice because I botched the error monitoring too. I fixed the game yesterday and the forums just now.
If you see any more problems, report them to firstname.lastname@example.org
Sorry about that. 🙁
