Hello Sykozen. As far as I am aware you can change your donator level from one characther to another by using the command /transferdonatorlevel IG. Although if you want to change your donator vehicle to another characther you will have to post a topic in the 'Donation' section of the forums requesting that. As far as changing your characther name you can do it IG by using the command /changemyname, but you will have to pay 25,000 dollars and it will have to be approved by an admin. Next time try to post this topic on the 'Help Section' of our forum.
I hope I helped you.
Escaper.
