Good idea. I miss it too. Mostly, I miss my original 75 or so tracks I lost when it was shut down. Luckily, I found a few of them on archive.org and the ones I deemed most important were saved in various formats and on different clouds etc. My handle was "Playkid" I loved interacting/collaborating with different artists and the feedback was very constructive at times.
Thanks for your post!! I hope this idea can be manifested.
