OK
Lets make a banner.
media.greenhorizons.org is what I suggest. Or greenhorizons.org/media
Then split it into visual and audio.
I am tempted to ask for a wiki and email list, although I can see we already have a forum and a blog that needs more users.
One thing that would really help is some documentation on organisation. Something from the top to set the goal posts and orient people so that they feel that they can contribute. Something that explains the structure, how to get involved, the aims and methods and the communication tools. This would allow me to invite folk to participate.
