Public-held Tier2/3 ISPs

Hi, I'm currently preparing a small paper on North American service provider economics (educational purposes). I'm missing some Tier2/3 ISPs which have public financial data available. Can anyone give a few names? The paper won't include company names (i.e. company x, company y), and besides I don't expect it to be widely distributed. Thanks for any Help! _________________________________________________________________ Join the world’s largest e-mail service with MSN Hotmail. http://www.hotmail.com
