Mortis recently dropped the following note on the SD boards:

On or about August 20th, 2011, I will be shuttering my W:ET message board and closing down my webspace. This means that access to my ETpro mapscript collection will only be available by contacting me directly either on this board or via email. Any and all are welcome to scoop up my scripts, or else re-host them at your discretion.
And re-hosting them is exactly what we're doing right now!
Download the full pack from our TrackBase Filebase !
In the pack you'll find the map scripts of course, as well as the original post of the author describing what each script does.
