A new building type "Weblink" has been added for 0.49.9. When a player accesses a weblink building, instead of seeing the normal stats about what it produces, they see a webpage displayed using the in-game browser. The owner of the building can set the URL for the page for each building, using the building actions menu.
The in-game browser is still very limited on what sort of pages it can display, but we will continue to enhance its scope over time. Until the browser is more advanced, i would not recommend giving this building out freely to players..
