I have heard allot about Nero and Nero's server and Nero's game.qvm. But i don't understand the Nero's server part. Is there really a Nero server. If there is how can i see it. And if there isn't a Nero server please tell me.
My friend has a server he wants to know:
How to keep server up without keeping your computer on all day while waisting electricity and how to make his server with the  thing at the begging to make server at top. Can you help me?
For Question 2:
I believe you have to keep your computer on to run a server, I know there are ways to do that but not in away you or your friend would understand. Most of these 24/7 servers are ran off Dedicated servers with no downtime or hosted from there home on a separate box. About the squares I doubt anyone will tell you that due to the fact everyone hates them and it places your server at the top of the list.
