What's the difference between sending and submitting, and how do I submit my completed challenge?

To answer these questions, it would be helpful to show you! Let's illustrate the difference between the two actions by using the following image:

Sending: Use the arrow inside the red square to send the AI your message, which the bot will respond to. You do not have a limit to the amount of messages you can send in the conversation.

Submitting: When you feel that you've gotten the bot to give you a winning answer which satisfies the challenge description, click the button in the yellow circle to submit the chat for automatic judging.

If you have passed all the requisite tasks for the challenge, you'll see "Challenge Conquered!"; if not, you'll get a "Not Quite There Yet" notification. From there you can either keep trying with your existing chat or restart and try a fresh attempt. You have unlimited attempts!
