I heard that once you have been a member for 2 years you get a Loyalty Box. But my question is do you get a Loyalty Box every 2 years or just once your account is 2 years old? Could someone please help me?

You get your first one when your account is 2 years old, along with the achievement. From there you get one every year. When you're a member for 3 years, 4 years and so on, with achievements too :)

You get a loyalty box every year after your account is 2 years old.

thank-you so very much for the help! :)
