Yeah. So I went through the Forums and so far, I haven't come across any rewards that one gets for getting a friend to use Alienware Arena. Yes, I understand the concern of one jobless person creating 100 accounts and getting a lot of rewards but on the bright side, it will make the website even more popular and gives a reason for a new user to spread the word. Anyways, let me know what you think.
Also, I felt like I saw 5 ARP per refer somewhere but I can't find it now. Anyways, cheers! Have a great day!
