The document describes a campaign to promote Sonera's music player service. Users can create posters promoting their own virtual "festarit" parties and share them online. For each click on a poster's banner, the festarit receives a "join" point. Posters will also be turned into banners for online promotion. The goal is to make a viral campaign that promotes both the music player and users' festarits. A website will be built where users can make posters, see others' posters in a gallery, and check a ranking of top festarits.
