Small business owners across Iowa can take part in a series of “web-cast” seminars on their computers today. In past years, the seminars were offered in a limited number of places via satellite, which forced people who wanted to take part to leave work and go to a site for several hours. Dave Lentell is spokesman for the Iowa office of the Small Business Administration, which is hosting the seminars. He says the first one begins at 9 a-m and is entitled “e-Small Business Challenges and Opportunities.” He says there are two other seminars available today to anyone who would like to watch via the world wide web.
