An article in the You will have noted that the design of this website has changed. This has two main reasons: first, I updated the publishing software, which had the page templates I was using stop working; second, I asked the vendor of the templates to update them, which did not yield a satisfactory response during the period I thought reasonable. Hence, after the problem persisted for months I decided to use other templates and redo the entire site. The look is different, but the content is the same. However, what will be lost are the permanent links to the individual blog entries. Sorry for that.
