Quick rundown on how to change login screens. Download the Login folder and decide which login screen you want to go with. After you make your decision, its time to make a new patch. When you create your patch you need to make a folder named "Interface" then make another folder inside of there named "Glues", then inside of Glues you make a folder named "Models". You can drag all of the folders from the download into the "Models" folder at this point. Also inside of "Models" make a new folder named UI_MainMenu_Northrend. You are now going to go inside of the folder with your desired screen, highlight the m2 and skin files, and drag them into the UI_MainMenu_Northrend folder. Once inside the folder, you are going to rename the files you just pasted (eg ui_dracthyr.m2 is now going to be UI_MainMenu_Northrend.m2) Do this as well with the skin files. When you are finished, close out of the patch, delete your cache, and start up your wow.exe and you should now be looking at your new login! Hope you enjoy!
