The host service will now send you an email when output goes into your log file for the first time. It's too easy for error reports to go by unnoticed otherwise.
To get this working, you just have to remove your existing log file each time and it will notify you the next time anything goes into it. (It sends the notice when the game shuts down, which I suppose might be quite a while after the output was generated in some cases. I can alter that.)
You will also need an email address registered with your key. To change it or see what it is, use the '.account set-email' and '.account info' commands. We will be upgrading the interface to all of those commands soon, but for now, those should at least be functional.
