Heya,
As recommended at http://meta.wikimedia.org/wiki/Mailing_list#Create_a_new_list, I've added this mailing list to Gmane at http://dir.gmane.org/gmane.org.wikimedia.usa.colorado -- that page is currently blank, but I think it'll get populated eventually. If it doesn't work in a day or two, please let me know!
cheers, Gaurav
