Hi vanilla, welcome to the Linux Mint forums
Thanks for giving Linux Mint a try and I hope you continue to enjoy using it! You can search for Linux native alternatives to Windows applications with this website: http://alternativeto.net/software/?profile=linux
Be sure also to check out the Community
website (ideas, tutorials, and hardware and software reviews), and the Cinnamon Spices
website for adding themes, applets and extensions to Cinnamon (and if you haven't installed Cinnamon, see here
a recent update for a teaser).
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
