Hi, Recently, I have been learning classic textbooks “Introduction to agent based modeling”, but there is no content on its website “[https://www.intro-to-abm.com/](https://www.intro-to-abm.com/)”. if it has been migrated to another address, if anyone knows, I hope to let you know, thank you! ---

You see a blank page? When I go there I see this: ![Screenshot 2025-07-31 at 10.29.26 AM](https://forum.netlogo.org/uploads/default/original/1X/0b31232501046529534a61c26325ecbc03531c97.jpeg) ---

This is the web page I see here, and nothing happened after clicking these buttons either. I tried to opening it with different browsers, but the result was the same. ![image](https://forum.netlogo.org/uploads/default/original/1X/2a2499328b713ff2d5f76816ba827ce9b0b367b7.jpeg)
