Dominic, I'm pretty certain it's not the way it works.
What Shirley is offering is her help as both a very experienced composer and as an harpist, to improve the harp parts of our compositions. Only that (as far as I believe), she'd like to have the scores she edits preserved. And also she's attempting to reunite a library of works for harp by modern composers, in a way that is easy for performers to access - but only upon agreement.
In this way, this would be actually helpful for both - we can improve our harp writing, and our works become accessible for performers. Nevertheless, additional explanation would be helpful.
