No really I did...

As you may know I am abit of a WordPress Geek. So I decided to use BuddyPress which is an add-on to WordPress to make things social. Its a public based social network where it lets everyone connect with everyone. You can create your own public/private/hidden groups and within those's groups you can talk in a forum styled environment.... Alot more to add because I have alot of things to do for it but here is the link anyways.

Activity - Lets Chinwag | V1

You could exploit some easy members to your groups if you decide to make one

PS the name comes from a common slang word over in the UK Chinwag means Chat just incase people ask
