Hey guys this is a guide to get goblins a playable race on your server!
BUT you do have to substitute another race for them, but you can always change it back. So first decide what race you want to substitute.
The race numbers are;
1 Human
2 - Orc
3 - Dwarf
4 - Night Elf
5 - Undead
6 - Tauren
7 - Gnome
8 - Troll
10 - Blood Elf
11 - Draenei
Now go to your database and open up the table, playercreateinfo.
Now the first set of numbers will be the entry id don't pay attention to that, the second numbers are the race id's so find all the ones for the race you want to change and scroll sideways till displayid which is right after Z.
Now just copy and paste 20582 into all the display id slots for your substitute race and restart your server!
