Text, Image, Video, Audio files — we call them all Records. And when you post something here, we call it releasing a Record. That's because you're sorta letting it go, putting it up for grabs, so anyone can download it, sample it, build on top of it, or otherwise Remix it from there!
TIP: Records can be contributed to as many Challenges as you like, so if you have a Record that fits the criteria for multiple Challenges, you can add it as a contribution to all relative Challenges! The sky is the limit! :)
