I have a craiglist like site to build. I want to add a feature where employer and employee can chat (1:1, very simple chat) if they are online, or post in private forum(1:1) if offline.

Any code out there? The client is paying too low for me to build things myself.

 

I found code but they are full featured forum and chat rooms/servers, I just need a plain and simple solution.

 

Thanks in advance

if(isset($_POST['Logout']))
{
	$mychat->putMessage($_SESSION['SES_USER_NAME']." has loged out at ".date("h:i:s a"));
	$mychat->delUser($_SESSION['SES_USER_NAME']);
