I found TIG's DXFlayerscols.rb, but it doesn't seem to do anything, at least for SU 8

I found a post at http://www.sketchucation.com/forums/viewtopic.php?f=180&t=23650&start=0, where TIG provides a link to DXFlayercols.rb. But I have to login to access the link and I can't seem to login and get back to that page without it asking me to login again (stuck in do-loop hell!).
