hi guys, im trying to figure out how social networks get messenger services for their users.... im looking to get and install a messenger, text and if possible voice chat...so that users can talk to each other. but im having difficulty getting specifics. i notice some social networks have skype installed on user pages and msn messenger, so that user can click on the users skype or msn icon and talk to them directly....but i have no idea how to get this feature for my own website, i have looked for hours to find the solution but am coming up empty. can anyone advise or give suggestions.. rehgards
