Vitne has posted over on his blog some tips and common errors for using CoPromote. If you are an independent artist misusing CoPromote, or unsure about what to do with it, check it out.
"CoPromote is an excellent tool for independent musicians to share their content. So if you are a musician wanting to promote your music, I highly recommend it. But PLEASE...do it RIGHT!
