If Daz3D picks your account for a random gift, you will receive an email in your main daz username email account. They are random and not all users will get one as far as I know. But knowing daz, I’m sure everyone will get something at some time. Maybe even if it’s just a new free item.
I guess I should have my kids check their emails…my teens each have their own accounts (yeah…and I’ve ended up posting in my daughter’s name a couple of times BECAUSE SHE DIDN’T LOG OUT…when she was on my computer).
