Simply fill out this form with all the required information and job is done. You won't be contacted any further and I don't make any guarantees that your track will feature, but if you watch the live streams you may see it if your track is good!
There aren't really any requirements for submitting your track - just be clear on what type of track it is when submitting the form. Anything that is mis-allocated in terms of track type won't be considered at all. One thing to point out is that if a track does not have capacity for 30 players it won't be considered for inclusion, unless it's a themed track.
Of course being well made is an obvious necessity and if you're at all doubtful of what that means perhaps hold off on submitting until you've seen some examples of good tracks as we go through the live streams each week.
