[Observium] Forced unsubscription

Hi Guys,

If you get force unsubscribed to the list directly after this, it's because your mail server is rejecting emails with "naughty" words in them, so you're flooding other users with bounced messages.

Please subscribe from an account which doesn't have draconian nanny email policies. (Because we all know it's impossible to change those policies, we don't even suggest you true, just use another account!)

Thanks, adam.
