I doesn't want to sound like grammar n@zi, but on the download page:

Quote"3D Rad v6.41 (latest update) isn't public domain yet. However, if you have supported 3D Rad development during the last 30 days, you should have received a download link to it. "

I think free for public does not equal public domain. Public domain means anyone can do anything, including sell 3D RAD (just like some people repackage gimp, blender, etc - what interesting is people don't mind people repackaging and sell linux though .... ). However, free to use mean people are free to use, but 3D RAD developer still has copyright on it though.

Anyway, here I am, observing from afar. Formerly known as Maniac Wolf (starting from 3D RAD 4.0 back then.)

I wonder if Mike Hense still here. There is username Mike something though.
