So, I didn't read the fine print. FeedBlitz, the service that provides email subscriptions for this blog, only provides it free for a little while. After that, they start to charge. Apparantly FeedBlitz needs to make money, which proves quite unfortunate for us.
So, for now (unless anyone can point us towards a free service, which would be great!), you can no longer get updates to your email account. Please check back often for news and updates.
