I don't think you have to make your apologies. You gave your meaning and you are free to do that. I just think that the overall meanings are too positive and not constructive enough. (don't get me wrong: not all meanings!). Thank you for you meaning about the models argument. (I agree with you). It is good to discuss about such things, and I regret that some persons took it too personally. That's the reason I don't involved to it, it wasn't a clear discussion anymore. Ionah
