Hi Fabrizio, welcome to the Linux Mint forums
Thanks for joining the forums!
Be sure also to check out the Community
website (ideas, tutorials, and hardware and software reviews), and the Cinnamon Spices
website for adding even more themes, applets and extensions to Cinnamon.
You can also chat in real-time with other Linux Mint users. In the Mint Menu, in the Internet section, start the application XChat IRC. You will automatically get connected to #linuxmint-chat for general chat and #linuxmint-help for support with other Linux Mint users.
Now that you are officially minty, have fun with Linux Mint
