Could you please give me some ideas on getting an e-mail list. No one is leaving their e-mail address on my website. Is there another way to get addresses of those who might be interested?

What listserv are you using for your e-mail list? Are you making it difficult for people to subscribe? Also, what are you offering potential subscribers? Are you sending your subscribers a unique newsletter with interesting and valuable content, or a page of ads? There is so much competition for subscribers that I believe you must give them something they can't get somewhere else. Ask yourself this question: Would you subscribe to your newsletter?
