Quite a little bit confuse with donation

[Thanomsak]

What does donation -$3+ do for? What can I access in that donation? and also in the donation.After I pay a money for a rank that I need to purchase.Do I need to reply as a post again to make sure that I already donate?

Unfortunately, you don't get a rank if you donate $3 to the server. You only get a rank if you donate either $8 or $12.50. You can add to the $3 to get the a rank if you reach $8 or $12.50. Once you donate the right amount, you don't need to post in the forums because the rank will automatically given to you in game.
