Third Party Content Official Usage Permission Request Template
Subject: <content type>
I am a <position> for the freely available Source mod "Empires" (empiresmod.com), and recently came across your <item> here: <link>
I was quite impressed with what I saw, and was wondering if you would grant Empiresmod permission to include your <item> with the mod by default. Coffeeburrito, a coder for the mod, has authorized me to communicate on his behalf in this regard. Our <position>s would surely love to make use of them, but I want to make sure you would be comfortable with that sort of thing. I look forward to hearing from you soon.
