Volunteer, With Questions
This sounds like a great start. I run SpiritPlants Radio (http://www.spiritplantsradio.com) out of Arlington. I've also been doing a show on the station for 8 years. Online radio is not too hard to do, and there are many inexpensive options. The key is to take simple steps forward, not try to go too fast. Is there going to be a meeting soon of this group? It would be good to talk about the technical issues, the logistical issues, and the creative issues of creating and maintaining a viable station.
I would also be interested to know what kind of content the station will feature. There are many options. I've signed up for the mailing list, and can also be reached at email@example.com or firstname.lastname@example.org. I'd like to help out, if possible.
