If you're not on the list and you even remotely have an interest in the second oldest fantasy RPG in the world then you should subscribe here. Right now. Now!!!
They're up to issue 3, and it's a great informational newsletter, really pulls together just how much coolness is rolling around in the Tunnels & Trolls community these days. Also includes regular updates on the status of the Deluxe T&T Kickstarter and where it (and all the extras) are at.
It's also cool because if you (like me) found Trollhalla's strange inner sanctum walla a difficult place to find regular information --but still want to be an involved T&T fan-- then the newsletter is the perfect solution.
