Haha, yea, it's the wrong thread, but that's alright.
I'll be honest though, I won't share my Steam collection, except with RL friends and family.
That's what I'm doing now, and it works well, but it's very limited.
It's a fun idea, but I don't think it would work well as a "giveaway" system. It's really made to share with a few people, I don't see it working with 10 for example. But maybe they'll keep working on the system
Sorry!
