Dear @DigitalPenChallengePreregistrants , We're almost there! Thank you for signing up for the Digital Pen Feature Extraction Challenge. It's been great to see so many of you join, and we can't wait to see what you build. A quick update on timing: we're putting the finishing touches on the challenge data, and we're taking a few extra days to get it right. That means the challenge launch and data release won't happen today but will come later this week - we'll announce the release date here when it is ready. We will post a follow-up announcement soon! Best, @DigitalPenFeatureExtractionChallengeOrganizers
