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).
