Question

Hi! We need to establish a new intranet for one of our customers using Share Point Server 2003. We are looking for exemplary intranet sites where we can see what are the main areas that are commonly covered by “todays” intranets to have an idea what is the typical content in nowadays big intranets. Links would by appreciated. Thank you gicio
