just signed up, would like to add to favorites or create shortcut
That’s a great question! It looks like you’re using Firefox to access the site, so you should be able to create a shortcut fairly easily by following the steps found here - Create a desktop shortcut to a website | Firefox Help.
If that doesn’t work for you for some reason, please let me know what operating system and web browser you use and I’d be happy to provide some more detailed instructions!
