We have covered this topic before, but I think it's important and very relevant to contemporary band management. And there are new members. I don't know how my band could get by without either tool. Does anyone have a band member in a busy working band that doesn't have either and what if any problems does it pose for the band? I want to use busy working band as the basis for comments and discussion because I don't think it's as much of a concern with the hobby jam bands.
