Hi, I've just joined, assuming I   could upload my music and fonts for game developers to use. But it seems I can't.
I have three albums worth of my punkband De Fuckups ( https://open.spotify.com/artist/2zBKQyLdZlM4aRoXEC6WfU  ) that can be used (they come with a Creative Commons "BY-attribution" license ) and  over 30 fonts I've designed over the years  that are  completely open source (https://www.fontspace.com/tup-wanders). Some even specifically designed for game developers.  
Can I upload these somewhere or how does that work?
cheers, tuppusfuckuppus.

...There's a category for game assets and another for albums & soundtracks. You can also choose an open source license from the metadata tab after you've created a project.
