First of all, these new ranks have only been given out to about 15 people.
Now that you've seen them and posted comments, we'll obviously make some adjustments.
Let me make some things clear:
1. If you have an old rank, and you donate more, you will get a new rank automatically.
2. If you get a new rank, you cannot go back to the old ranks. (This may change.)
DO NOT PM ADMINS ASKING FOR YOUR RANK TO BE CHANGED!
The donation center has to be re-done as it's slightly outdated and needs some enhancements. I plan on updating it with these new ranks, how they work, and also with the policies regarding donations. I also want to add more "self-service" features so you can manage your ranks and donations on your own.
Keep an eye on this topic of the donation center for updates.
