I think you’ve got me confused with other posters.

Thank you. This is a helpful style of posting: reading it, I can easily
tell what your point is. If I didn’t know this already, I would come
away better informed.

I understand that he gave the link for general information. That’s
great, and also very helpful. It would also be helpful in response to a
specific question.

But if you send someone to a self-styled “university” front page to make
one point – how are we supposed to know which point the poster is trying
to make? Yes, we can read the site, and also come away better informed –
but it’s a lot of work for *all* readers, when the poster could
summarize and save everybody else’s time.

So I was trying to make sure there wasn’t a point that needed to be
clarified.

James.
