Agree! 
But I think I shouldn't be the owner of those accounts, they should be owned by Csound. Is that possible?

I mean, I can create them (and pay their fees where required), but then if for some reason I won't be able to keep them alive they could go lost.

That brings up again the "Csound Foundation" topic.

To make an example, the Chunity package (Chuck on Unity, https://assetstore.unity.com/publishers/35740) is published by the Music, Computing, Design Group at Stanford (mcd.stanford.edu).
