Hello again. I just wanted to write a quick post to say that I am still studying this thread. I appreciate all the helpful contributions and would like to specifically thank Benson and jldiaz for their amazing explanations.

I am learning a great deal here. I feel that the willingness of the folks here in forum (especially the aforementioned users) really demonstrates the true spirit of the open source philosophy and the things that made the internet great for sharing knowledge among users.

I am going to study the recent posts more closely and try to formulate some intelligent question which I will, hopefully, post tonight.

In fact, does anyone think maybe I should compile the info in this thread for a wiki entry?
