Re: agent/chat technonlogy
Depends on the software, there are many many irc type programs out there. Also one downfall of live chat is that you MUST have someone manning it, or it defeats the purpose. If you have a live chat button and someone uses it, but does not get a response it shows that you are not being responsible to the resources you are supplying and thus you would lose the users confidance and I feel they would likely leave your site.
