Zingtree now has a Wizard mode for creating new trees. This makes it even easier to get up and running.
The Wizard asks you for a question and possible answer options at each point in your tree. You can also provide a solution as well. This process continues for each part of the tree that is unresolved. As you continue, your tree is built, until no unresolved paths remain. This is the same process a professional knowledge engineer would undertake.
Try it yourself by creating a new tree at Zingtree.com.
UPDATE: The Wizard has been updated with a Live Preview option. Read about it here.
