I'm by no means insinuating that the bottom corner should be the only form of advertising the chat. I agree that you need to constantly have the offer of chat in front of them. I'm only suggesting the tight integration of chat with the site.
I would be interested in hearing your suggestions. We get some of our best ideas from the dealers. If you want something customized we offer that as do most chat providers. we did some custom work for Joe, you can see it at htttp://www.usedcarking.com. Tell me what you think. It integrates very well with his site.
He is obviously playing with the dropin being on the home page so you may or may not see it there. Oh, there it is....give it about 15 to 30 seconds.
