The INDEX was a good idea that I never had time or patient to finish and till some days ago refereed to only a small part of the blog. Now it is complete and you can just go there, find what you are interested in and you will have a direct link to the subject.
You can access the Index on the lateral right bar under PAGES: you can select HOME (the blog) or INDEX.
Also a good new: for the first time the blog went over a 1000 hits a day and for several days. The record is now 1292 hits on a day. Thanks for your interest :-)
