My boss wants to implement a customer support feature on the site. I am sure some of you have seen these things, there is btn that you can reach the operator online, and ask questions etc.. I have no idea how this is done. Is this a php thing? A service?

If you have fantastico on your server, then you can use the built in modules, if not, then try searching the web. Alternatively, you could spend a very long time on creating one yourself in either PHP or ASP. Try something like http://www.hotscripts.com for such a program.

PS, only make one thread. It probably messed up on you, and the mods will delete the one that hasn't any replies, or little replies of no-help.
