You can only donate via paypal at the moment.
We dont have auto donation yet, so you need to do the following steps :
1. The best thing is if you contact lblood before, as its his paypal so he knows that you are going to donate.
Tell him what you are going to donate for.
His paypal killduber@yahoo.com
2. Go to paypal.com
3. Send the money that is required for the item/rank you want.
4. If you havent told him send him a email about what you donated for.
5. In the mail you need to have proof that you donated for it, Transaction ID and the email for example.
6. When everything is done either Lblood, Me(Axel) or Nate will give you the rank/item
