The TrekBBS in-joke is more obscure even than that. Back before "The Andorian Incident" even aired, there was a topic in the Enterprise forum started by one guy who was very insistent that the show needed to depict "Andorian Ice Powers," which he'd learned about in "the sourcebook." It might've been the infamous Major Barcalow, but I want a second independent source before I say for sure.I believe the "ice powers" were from the role-playing game supplement that was the source of Enterprise's portrayal of Andoria's climate and culture in the season 4 Andorian/Tellarite/Romulan arc.
The original thread is lost to history, but Google brought up some other references to it.
