I've just gotten the glyphpress discussion board (http://glyphpress.com/discussion/) up over on the glyphpress site.
On it, you can find discussion about the rules of Shock: and Under the Bed, including errata and clarifications.
Also you'll find a forum for science fiction authors to critique each others' work, often inspired by Shock: actual play. This very interesting and active part of the forum is only visible to registered users, so apply for membership to read and participate.
The new forum is now running over inside xenoglyph (http://glyphpress.com/talk/forum/) and is frankly much better. The old one exists as an archive for those with old accounts, but isn't taking new applications.
Were the old accounts ported over? (I've tried to log-in with mine but it does not recognize me. Figured I'd double check before I re-register.)
Nope. But if you've ever commented on my blog, you've got an account. And if you haven't, it only takes two seconds to get one.
