Can I send a message to my subscribed players?

I would like the ability to send an e-mail notification of my own devising to my subscribed players. If there is a last minute cancellation I'd rather not rely upon them going out to the web page to look at the information.

You can send a message to the players subscribed to one of your own campaigns through the calendar admin. Just choose the campaign your notification is about from the "Send Game Message..." menu. This menu will only display if you actually have any campaigns that you can edit.
