Hi Timothy, 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). 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.
Though I gather you enjoy KDE more than GNOME, have a look at Cinnamon which is the new user interface being developed by the Linux Mint developers. See
here the most recent update for a teaser, and see the
Cinnamon Spices website for adding themes, applets and extensions to Cinnamon (and check out the
Cinnamon Extras package, which will install a lot of these for your automatically).
