I just bought my Silhouette last month as well. I've found You Tube to be a huge source of information! There's so many tutorials! I've learned how to add free fonts, download and add free digital papers, as well as print and cut and how to upload free SVG files. It's all on You Tube!
I even figured out how to take designs from that other company and convert them. I cannot teach it, however it is possible to do without buying carts. It's something everyone needs to figure out on their own...unfortunately. There's a bit of a learning curve!
Hope you all are enjoying your machines. I have fallen in love!
