Sup y'all, 
I'm currently making my own server for VC-MP, but i got some questions; 
How can i add my own commands to the server? 
Commands like /help, /commands, /register or carspawn commands 
How can i add my own text to the server? 
Like if someone joins my server, it says "Welcome to my server!" or something. 
When i put my server online, it's only for the people that are on my router. How can i make it that people from over the whole world can join my server? 
Thanks for the help  , 
TroniX.
