His website(s) are full of exactly this type of thing. And I have to agree. I can't count the number of questions I *haven't* asked on this list, because I built a page to test a particular concept. And this sort of activity (as opposed to just reading about something) really locks in your understanding of a concept. Paul -- Paul M. Foster

I consider the thread answered and solved unless someone has anything more to add.

I will say this, though. I have yet to figure out, from your URLs, how your site(s) is/are organized. Maybe a reorg would help? Paul -- Paul M. Foster
