I have used some old scripts (version 1.xx fully loaded), for a website. It's unbelievable how good this works, after all these years. However, I wonder if there will be (near) future troubles if hosting providers update their server's php versions, because I know and experienced that this might happen.
» Quick.Cms v1.x
Pages on versions 1.x-4x are pages that are owned by gamblers :)
