I have started to use posts-to-posts plugin by scribu, and now I need to change vaues for connection fields. Particularly, I've created 'person' and 'piece', connection 'role' in between and defined possible values for role as 'composer', 'conductor' -- but now I think that I need rather 'author', not 'composer'.
Please, how to do that? I could experiment with phpmyadmin, but I wouldn't like to loose anything in progress.
Thanks!
