Was looking around the ArcEmu Wiki and saw some very interesting pages that I thought I would share with the community. They have helped me out alot and i'm sure that most of you don't know half the things that these links will tell you, check them out:
[SQL] Information on how the 'Create_Proto' works
[SQL] Information on how the 'Create_Names' works
[LUA] Information on different Lua Unit Commands
[LUA] Information on spawn help and teleport Unit Commands
Thats all I could find for now, if you have any helpful links, or want to request some please feel free to post!
