The most successful web sites consist of content rich sites forming a community of people interested in that content. Community portals combine the key top level activities into a single site with a view to saving users time with accessing numerous specialist sites.By posting details of your site on a portal, not only can you get free hosting, but free publicity for your web site, something you may not be able to achieve with content specific single sites.
The social networking web portal offers, chat, friendship, advertising, uploads of photos, music and video, groups, clubs and forums and potentially more features, all sections can be created by the members, personalised and contributed to or viewed by other members of the portal. Membership, in the form of a simple registration is normally compulsory to access most if not all the main features. A single membership allows total access, thus making the portal a simple one stop site for all normal social, personal and business relationships, a big plus over having to remember potentially dozens of logins for separate sites.
