Question: What are the commonly or frequently asked questions (FAQ) about creating a competition on Kaggle?
Answer: ### Where can I get a dataset for my competition?

We recommend that you source your own, since it’s typically best to use data to which the participants do not have access (to minimize the temptations to cheat). But, if you don’t mind it being fully accessible by participants (e.g. for a purely educational competition), consider browsing Kaggle’s Datasets platform. It hosts thousands of public datasets and has rich search and filter tools to help you find something that fits your needs. Each dataset should include a data use license, which will indicate if you can use it for your competition.

### I’m receiving [an error]. How can I resolve it?

Start by reading through this setup guide. If you still can’t resolve the issue, try asking other Community Competition hosts in the Kaggle forums.

### I want to run the same competition again. Do I need to start from scratch?

For now, you are not able to clone a past competition. You’ll need to start setup from the beginning.

### Who can see my competition?

It depends on the privacy setting that you chose. Kaggle has 2 privacy settings – public and limited. Public means that your competition will be listed and discoverable on kaggle.com. Limited means that only people with the provided URL can view and join the competition.

### Where can I find the invitation link?

If you selected Public, you can share your competition from your browser tab – anyone can see the competition. If your competition is set to Limited privacy, visit your competition > Host > Privacy > URL for Sharing (if you’ve selected Limited).

### How do I contact support?

Unfortunately, we aren’t able to provide hands-on support for setting up or troubleshooting your competition. But, if you are experiencing an issue that you believe is affecting the entire platform, please contact us. We also encourage connecting with other community competition host on Kaggle’s forum.

### Can I offer a prize for a Community Competition?

Unfortunately, a cash prize cannot be offered without additional paperwork with Kaggle. If you’d like to run a competition with a cash prize, please reach out to our Kaggle Competitions Team, who can walk you through the necessary steps.

## During Your Competition

### Can I invalidate or delete a participant’s submissions?

Yes, go to your competition and navigate to: "Host > All Submissions". There you can hide specific submissions.

### Can I upload a new solution file and rescore the competition?

You can upload a new solution file, but you cannot rescore a competition on your own. Please upload a new solution file and contact support. An administrator can rescore your competition. Competitors’ new submissions will be scored against the new solution file.

### I would like to download my participants’ email addresses so I can email them for a new competition. How do I do this?

Due to privacy regulations, you cannot currently download the email addresses of participants.

### I want to give participants more time to compete, how do I change my competition deadline?

If the competition has already ended, you should set up a new competition, as participants will have seen the private leaderboard. If the competition is still active, you can change the deadline by going to: "Your competition > Host > Settings > Deadline".
