How to make a Verbot® fire a Rule without Input.

<send text>

Is used to fire a Rule using text as the Input within Output.

Example:

Output: "Your answer was correct on that last question. Get ready here comes the next question.
<send nextquestion>"

"nextquestion" is the Input for another Rule. Once the Verbot speaks the text "Your answer was correct on that last question. Get ready here comes the next question." It sends the Input "nextquestion" to itself, and fires the Rule that matches to that Input.
