Hi, thanks for invitation, but I am not interested in participating in SG groups anymore at this moment, and remain active on SG mostly because of another group admin/mod duties.

Another thing, I don't care about winning chances or "getting" some value out of Steam Gifts. I value the most when people really mean it when they enroll to giveaways and play the wins. If they make mistakes by winning what they don't like, learning from these mistakes. Playing the gifted games is the obvious, intended way to appreciate and return the gifter's goodwill and sentiment, and abstractly thank the whole SG community and site. Only people who enable themselves to deeply experience the joy of good things happening to them can return the joy back, so good things can flourish and multiply.
I was considering the fairness of giving something back to community as a virtue too in days long gone, but this was when I was making a mistake assuming that people play the wins fairly often. The more you know.. ) I stopped paying attention to ratios after realization came.

I also remark that for many users including the new ones and these who visit the site rarely, it may be a great experience to see once in a while great wished games being given away and accessible for them to take part in GA even if chances to win are small. This point of view gives me own joy when making public giveaways, alas absolute majority of winners do not play the wins, reducing the magic to a joke.

So I have been mostly torn between two audiences for giveaways, never finding a really good solution in the boundaries of SG mechanics. As you can see, neither fits your group ideas anyway.
