I actually had this in my sig at one point, but lost it. It was a site that creates random ads based on keywords. For example, my keywords were "import atlanta". It would create ads in my sig like:
"I get my kicks at Import Atlanta" or
"Nothing says performance like Import Atlanta"
Those random ads changed every few seconds or so. Does NE1 know what I am talking about? Prolly not since I barely do - LOL.
