Hey Bro,
Just so that you know, Fiji Web Design Technologies is currently designing a module of that sort which will be compatible with the Community Builder and displays user Photo and profile link. When you click on his/her image display, it will take you to his /her profile page. However, it is still under production. As far as I know it will run off Apache and can be built into newsletters or e-mails. So that when a user checks his/her e-mail online and views the newsletter or e-mail, it would also display the users online at the time. So in your case the user will get to see which DJ is currently on Air and will also have a link to his/her profile page. But the DJ may have to log in before he goes on Air otherwise he could make it out that it runs under the server time or something of that sort. It is currently under production at the moment but if you contact
bucabay@yahoo.com, I believe he could most probably script something special for you. Just tell him that Navstar sent you and refer him to this post. Alright, hope that you find what you want .
