After pitching, it is time to form teams. This is supported by the page which I would recommend to hide until right after pitching. There are many ways to do team formation, and you should adjust the page accordingly. If you are forming teams in a meeting, you might not need the page after all. Our Hackathons are across multiple offices and time zones, so we built this page to support a more chaotic self-driven team formation, where every participants goes to the page and follows the instructions on the page to pick a team themselves. There are two important points at this stage. When a team is formed and the participants are committed to working on the idea, they need to mark the idea as funded (by pressing the button on the page). That moves the idea to the next stage, we now know that it has a team working on it, and that there will be a demo at the end of the Hackathon.
To undo funding, a project can be sunsetted (by pressing the according button). That should rarely be needed, and you could hide or delete those columns if you do not want to use it to avoid the complexity.
The next page is and intended as a place for the different teams to organize themselves, track their tasks etc. Hackathons are chaotic, and it can be tricky to collect information about the projects once a Hackathon is over. That is why I encourage to you have the teams work out of their team page as much as possible, as opposed to their own docs which might get lost
