For those of whom want to be lazy about getting the titles but dont want to make a macro AND autoit script :
Run Warhammer in windowed mode
Invite your friend to a party.
Remove all armor, all weapons, everything. Both of you must do this.
Press Escape, and go into keymapping. Set "Target Self" to F1, and "Target Group Member 1" to F2.
Both you and your friend must download it.
Both you and your friend click the .exe!
Wait until it finishes targetting you and your friend.
Repeat until you get the title: Emperor.
The .exe is just a compiled .ahk file, all it does it spam F1 & F2.
The credits for this actually go to "Sprackle", not the poster of this thread nor me.
