Anyway, you are right. I haven't said much other than what was in the original article. In fact, I worked very hard on that article for about 4 weeks, making sure that it said everything that I wanted it to say. And I rewrote it from scratch a few times in the process. So, because it was an attempt to comprehensively cover a particular topic, I am not surprised that all I am doing now is restating parts of the article. In the process, I am hoping that certain things that were overlooked or not understood are becoming clearer.

And I am disappointed that many questions in the chatterbox have not shown up here. And I am disappointed that no one is discussing the relative merits of these 2 modules or other related modules.
