Ask the server owner, but don't be surprised when the owner doesn't answer you. Private server owners usually only give GM status to their friends.
Only a GM/Gms of the server can do that.
If you are referrring to a private server, then yes, only those who have control over the server (or people they give such power) can use GM codes.
A GM should know how to do this. there is a certain code that only a GM can use on private servers. you can google GM private server commands and get a list.
yes you can. its one ability you get if you are a server gm.
you have to figure out a lot of coding to do that.
There are no GM power hacks on retail (legal) servers. There might be on private servers, but private servers are illegal. We can not help you with that here.
doing so would mean hacking into the server host's computer which is illegal although you probably already knew that.
A private server on World Of Warcraft is just that, a private server on World Of Warcraft.
Ofcourse!... Assuming you're a GM at Blizzard's HQ, or running a GM account on a Private Server. It was possible to get to GM island a long time ago: but since then Blizz have greatly increased their security with such built-in programs as "Warden". As far as I know, you can't get to GM island, as it's set up on another server unreachable by any means: Unless hacks ofcourse.
A private server on WoW is a server made by someone else than Blizzard. But playing or creating a private server is very illegal, so i wouldn't recommend playing private server.
Pasta doesn't need a private server.
