//THIS IS WHERE YOU SET WHAT DOMAIN YOU WOULD LIKE TO USE.

var Domain = 0;
//0 = Derpibooru.org
//1 = Derpiboo.ru
//2 = Trixiebooru.org
//3 = Krausbooru.org (see note)

//Note:
//Krausbooru is an experimental version of Derpibooru.
//Uses "derpibooru.org" with a vastly improved 
//and more aesthetically pleasing GUI.
//Use at your own risk.
