This sounds like a great service. Networker Cafe is an online service company supporting network marketing professionals. They have recently launched a viewer-driven online PowerPoint capability called Online Marketing Showrooms.
Online Marketing Showrooms enable any network marketer to upload a personal PowerPoint to a unique Web location where interested visitors can view it at their own place and whenever they want. In addition to presenting marketing material, Marketing Showrooms also support capabilities to capture onscreen information entered by the viewer. This permits viewers to leave questions, enter contact information, request phone follow-up, or respond to special promotions.
