Question about donation.

I was thinking about donating but the server is currently offline so I will need to wait, I guess. To all the donators, I don`t quite understand how you get your rewards after donating, do you just post a message on the donator section and say you donated or go to some other website, I`d heard about using the chatbox and also something about PM an owner, I`m just kinda confuse, can any1 give me some tips

Derp.

Or be lucky and see Alpha ingame and say, " Yo Alpha give me prize"

Thanks for your help, all I want is to make sure how should I donate, I am worried that if I can't make the payments correctly then Alpha won't have the money and I won't have the rewards. TY TY
