I sell advertising spots in my newsletter. I can actually make a few hundred a month from it when all of my spots are filled. (I limit the number of ads per newsletter.)
Still, it's not a full-time income, and I don't see it as being able to produce a full-time income.
Is there anyone here that makes more than, say, $2000 a month simply from selling ad space in a newsletter or an ezine? If so, can you share how you got to that point?
