All this web site was written and created by Johannes Norz, an Austrian network specialist, Citrix trainer, blogger and consultant.
Johannes allows to link to his blog and guarantees to be owner of all media used in his blog. Johannes allows to link to this web page, even if your website is a commercial one (this statement follows verdict Az. C-160/15 of European court of justice). This statement sounds stupid. It is! Like the verdict itself.
