Hi Arif, welcome to the Linux Mint forums
Sounds like you will know your way around Lisa already
I hope it will continue to serve you well.
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
the 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
