Dear Colleagues and Visitors
Maintaining and updating the site requires a lot of time and effort. Therefore, we are forced to introduce a partially paid access. We expect that the costs will not be too burdensome for you, and your money will help us in the development of interactive keys, and more dynamic updates of the site.
Hope for your understanding and thank you for continuing interest
