Ok, i'm not sure.. but i want to promote my website the good way: give to recieve and I would like to post a link to my giveaway. I am not sure, if i may post the link to the giveaway on my website: would this be considered as spam, or may i post it right away? Otherwise as in title, i'm willing to give away Natural Selection 2, if you don't want to participate in the giveaway you can still buy it for low price on humble bundle
