Hi Teemu,
Like Jami mentioned, the tool is currently working, although it is still deemed to be "beta". My team is working with colleagues in Learning and Evaluation and Community Tech on roll-out plans that include better documentation for interested users. We hope some of this documentation would be ready for you when you start using the tool in January, but please play with it know to see if you have questions before then.
We are also eager to know if you encounter any bugs along the way!
Cheers,
Tighe
