Here is a video showing you how to combine two contact lists from two sub-sites into one simple web page on a top-level site using SOAP services. I briefly walk you through some of the fundamental SOAP and web service concepts. However, there is much to cover in web services and this video addresses only one small aspect of a massive subject. With a length of eighteen minutes it is one of my longer training videos. You can fast forward to the 5 minute mark if you want to omit the SOAP and WSDL tutorial.
