Private servers are Legend Of Mir servers which are private. They consist of most things mir had before 1.5 update (1.4 server files). The setup is nice and easy providing you have a good understanding/knowledge of PC's. If not it may take some time to get get used to. The Private servers can be played on by people that want to play on the server using the IP wich can be found on windows xp by:
Start -> Run -> 'cmd' -> 'Ipconfig'
Read: IP Address.
Private servers can have things added to them that are custom made providing they have the correct resources etc. The game itsself is require to have a client so people can play (the one you download from
www.legendofmir.net) Private servers can add/remove:
NPCs (Quests/etc)
Mob spawns
start places / townteleport spots (Safezones)
ServerFiles may be hard to get used to but when you know how you'll have a average server.
