have recently received questions wether Karchan is secure, depending on behaviour that people see in their browsers. Well, truth of the matter is of course that I can never be 100% certain.
I do try very hard to increase the level of security of the game at every opportunity. It already has been strengthened considerably since the days of Drupal.
That said, I felt the need to write a permanent page and add it to the website, to detail how you can play the game in relative safety.
You can find the page here and it is also accessible from the Help menu. Choose Security.
High regards,By Karn.
