Welcome Diniana!
CND definitely is the place to be for the best in events such as Champions League, Pink Saturday Nights and Global Madness as well as the best selection/convienience of hunting/mining/crafting/sweating and such.
The shops in CND offer a wide variety of everything you need to enhance your fun and show off your style in Entropia Universe (E.U.).
I'll also mention NEVERDIE has great streaming music which you can listen to by selecting the "Radio" tab on the homepage and run it in the background while you have fun in any of the Domes, Discos or just "hanging around" in the Control Room. Currently NEVERDIE is also providing live commentary during the Global Madness and Champions League events, something you don't want to miss!
When you need a place to stay, apartments are available at CND too which you can decorate and entertain or store/display items as well.
People are usually very friendly and will answer questions in the Control Room or feel free to p.m. myself or any of the Moderators.
Good luck in your adventures here in Entropia and hopefully I'll see you up on "the Rock"!
