From their (newly revised) FAQ:
Can I run an online game via email, Skype, Google Hangout or a play-by-post forum?
Yes, you may run online games via Skype, Google Hangout or
play-by-post forum provided you to do not post or upload any transcripts
from your playtest, upload any playtest materials and make sure that
all members of your group have signed up to playtest through the
official playtest sign up process.
Well, woot! Who’s looking for another player in their DnD Next playtest? I’m up for experiencing it from the other side of the screen, for once.
About f'n time! 😉
Glad their lawyers are finally applying some common sense.
Well, except for that whole not uploading a transcript thing. That's a bit silly.
What? Friday ain't soon enough for you?
