Alpha sheets can now be added to games via the edit option in the alpha sheet display. In addition, statblock embedding should also work for the [sb=show][/sb] tags. Any problems, please post in experimental features with links to the sheet and the game.
The issue was that until you have posted to it, the thread doesn't tell you anything about anything. Just found a subscription option for the forum itself, though it is only daily, hopefully that I will help.
