It was December 2011 around the time I did my first GI8 - Scared Stiff. To be exact, Dec 1 2011, 01:27 PM when he gave me permission and Dec 7 2011, 12:14 PM when his follow-up said "Feel free to change whatever you want in your mod" 
We'll see if we can combine our projects and if my lose timelines / limited VP collaboration time can work, but in any case, at some point there will be a MOD / update of this table 
So following the logic here, if xgon gives his mod to jimmy, jimmy would be able to release it? Since he's got the joker card ("feel free to change whatever..")? Honestly, this seems a very bureaucratic approach, which is usually found at inefficient governments and not in open minded communities.
Noah, maybe you should have a look at the CC licenses for VPF? I mean releasing tables without any kind of licensing info from the author is asking for trouble. I would propose that authors must choose a CC license, which will then clear up any kind of modding or redistribution questions. Right now the situation is not very satisfactory.
