Site credits and copyright

Greenvoice is the work of many people. First and foremost amongst those people is you – thank you for creating interesting content and compelling campaigns and submitting them to the site. Everything you create on Greenvoice remains under your copyright and in your control.

The Greenvoice site itself, and the content in the Greenvoice Blog is produced by the Greenvoice team, past and present. However, we also make use of work created by talented artists and developers outside of Greenvoice; here we attribute those pieces of work and show our appreciation to these people for helping to make Greenvoice possible.
