Do go ahead if you would like to do that, and do a mixdown yourself also.
I had considered this project "Finished" long ago, and set the project to that status. But then we found that when Enrico wanted to try some work of his own that he was not able to upload tracks to a "Finished" project. (Blocked by the Kompoz system.) So I reset the project status to "In Progress". The project is now left open for anyone to enjoy playing and mixing and uploading if they wish.
If you make a nice mix it might be a good idea to send me a personal message, to alert me - then it could become the Featured Track.
