I'll followup with the SpeakerDeck folks. I expect they'll have it working soon. I think they got slammed a bit more than they expected, but they're throwing more resources at it now.
Gotcha. I passed it along. I'm sure they'll get it sorted soon. If you'd really like it now, shoot me an email, and I'll send it along. garrett at nextupdate dot com.
Permissions fixed. Sorry!
I know you meant "got slammed" but getting "god slammed" is probably how their server felt.
