Blog Checker requires a minimal configuration before you can start the website viewing. Thus, the Categories tab allows you to enter various nodes or subnodes, representing the website types. You can easily modify the structure if the categories and subcategories of each link are of importance. Otherwise, if all the URLs belong to the same category, the tab can be ignored.
The Settings tab is where you load the text file containing the website addresses, as well as where you set the log file. It can also display the contents of the text file you imported, as well as the status of each URL.
