From what I've seen in other "competative" bulletin boards, mixing different types only leads to flaming. This is most evident in the sport team and the automotive bulletin boards, where cries of "Die Green Bay Packers" and "No Mustang can outrun a Camaro", run rampant. I'm all for for keeping it for HL collectors. Heck, we fight enough about LE, GLOW and LLOM enough as it is!
