Upon completion of all challenges you will unlock a new feature: permission to upload your own challenges. From the ADD CHALLENGE menu, upload the source, compiler options along with a PoC. All of the uploads will be moderated and only the creative ones will be chosen.
- Do not share solutions or flags publicly.
- Do not brute force (too much).
- If you find a vulnerability that would impact the website/challenges, don't ruin the fun for everybody, report it to us.
- Most importantly, use common sense and show good sportsmanship.

Due to the host platform (DigitalOcean) upgrade, all challenges are currently offline. Unfortunately, there's no ETA for the fix, but I'm in constant communication with their support team. I will send an update here and in discord when the issue has been resolved. Thank you
