Copy and pasted from here:
I'll make this short and sweet:
We are trying to make a master credit list of everyone that has submitted markings to Onowl.
Post here with a link to your marking pack and what name you want to be credited by.
By the end of production if we have your markings but you have not stepped up to claim them, we will not be adding your name to the credits list. Considering there should be a great deal of time between now and the games final release.
If you have not submitted markings to Onowl then you can still link the files below for review and those accepted will be added to this list.
All you need to send is the PNG marking.
Once again, the thread is here
