Hi, new member here. lost with where to upload the mixing for the comp.

Hi already (i guess) download the files to mix "El train".
But where do i upload when i finish?

Hi Nastika! Just upload the audio file to your profile - you'll see an audio tab on your profile page, then click the plus button and you can add a track to your profile. Once done, just post a link to the track on the remix comp forum post....
