Before you go on Tombo, can I interject?

Andy, when I started this thread I referred to Tombo's attack, not on megaraks but on "rationalist megaracks". That's the point, that's what he meant, and I understood him to mean and everyone here understood his meaning and it has enabled this discussion to go on. Language evolves, and words tend to their most convenient meaning. You may have invented it, but it means something different now, here certainly, why else has no-one else queried it. I like it's new meaning, it's very convenient. I think you should accept it now. If it gets to the dictionary as your meaning it'll be way out of date.
