I see you've just pushed an update to the Farms Theme pack. From your instructions, I've got to download this to my local machine and then upload it to my server.
I'm lazy, I've got shell access to my server and it has a much faster connection than I have on my PC.
I've tried issuing a wget command from my server to download the link. This fails with a 301 redirect to the premium.wpmudev.org/wp-login url.
Is there a way I can construct this url to show I'm authorized to download this by say adding my api key as a querystring parameter?
