Do you have any videos or tutorials?
No, actually, we don't. The intention is that you can start using Scrumwise without any training, and just explore the tool as you go along.
Scrumwise has a very large amount of functionality - much, much more than you see when you start using the tool. And it varies a lot from team to team which functionality is needed. So, we prefer that you discover the functionality you need, as you go along, without having to know about, or even see, any of the functionality that you don't need.
