I think it would be nice to have a chart of machines and the motors that they use as a compare contrast. But I would definitely vote for it to be a members only list. For instance I have a Treasure Chest and only know that it uses a German motor. I have assumed Fullhaeber or Graupner but this is an assumption.

As for attitudes, I think you have just gotten a wrong impression from the written word in contrast to the spoken one. It is difficult to ascertain intention and emotion from the written word and sometimes we read animosity where there is none. I am fairly certain that Allie is just trying to help. I don't think she is giving you any attitude.
