A lot of the content is hidden from the “normal” visitor. This has two simple reasons. One is copyright issues. In the past I have repeatedly heard of incidents where colleagues had to remove things from their internet portfolios because the copyright owners had complained. To avoid this, I have a LogIn. The other reason is of course, that I also notice who is seriously interested in viewing my site.
So please don’t hesitate and write me a short note for the LogIn.
