Yeah, this is true. I have a copy of the file, and a link to it on his webspace. If you didn't join the [RTB] Experimental server with 15/16 players (it would tell you that it was full), then he didn't post it. Only people that tried to join the Experimental server are on that list. MCP posted a link to this file from the wikipedia entry for RTB, so there's no question it was him.
