integration of wordpress (or similar) into Social network

we have purchased a social networking software. (webnetwork) Its php and we have 100% source code. see it here: [login to view URL] but our client needs the social network site to also be a "portal" site as (lots of interesting things posted by the site admin..not just the members.) this is great software and people can sign up, add videos, blogs, pix etc.. BUT what we also want is for the admin of the site to be able to post things to the site themselves (videos, news, articles etc) using a master admin area. see this site [login to view URL] it has articles, features etc all posted by admin...WE NEED THIS FUNCTIONALITY. We think the easiest way to get what we need is to use blogs for all the things we need to add to the site (video, polls, news, photos etc). We are big fans of word press and think that wordpress would be a great way to add our content, images..news articles etc to the site....without having to completely redesign the webnetwork software Mainly it will be the home / landing page that has these features. So we need webnetwork (our software) to work alongside (or integrated) with WordPress. so our client can post items to their site from their admin area. Questions..lol Garfield
