CamMuso was the brain-child of the Faculty of Music at Cambridge University. They had, previously, an email list that students could use to advertise their concerts to other members of the University. The only problem was that with so much music going on, most people just treated the adverts as spam.

Bring in CamMuso. It allows people to add their concert or message to the site, which is then automatically compiled into a daily digest email of the events happening that week. People only receive one email, nicely formatted, of relevant concert information.
