How prevalent is Spam?  According to Scott McAdams, OMA Public Affairs and Communications Department (www.oma.org):

Studies show unsolicited or junk e-mail, known as spam, accounts for roughly half of all e-mail messages received. Although once regarded as little more than a nuisance, the prevalence of spam has increased to the point where many users have begun to express a general lack of confidence in the effectiveness of e-mail transmissions, and increased concern over the spread of computer viruses via unsolicited messages.
