Adding a department starts with clicking on the 'Add Department' link in the in the upper left part of the menu of the 'Show company details' screen. A screen will appear like the one in the next picture where you can enter the name of the department.
The add department screen.
We enter the 'Sales' department and click on the 'Enter' button. We are now able to clink on the 'Change' link to return to the screen we saw earlier but with one small change. It is now also possible to add a url to a website related to this department (off course you are free to enter a completely irrelevant URL here but that is beyond the scope of this manual).
