Dear Serge,

Let's clarify this. There are two independent services provided by CodaLab (both accessible from

- CodaLab Competitions, in which you can organize and participate in challenges, a.k.a. competitions
- CodaLab Worksheets, in which you can run machine learning experiments in the cloud, using notebooks

Also, is an old instance of CodaLab Competitions, not used anymore, but kept to archive old competitions.

Best regards,
