Updated the rules slightly, hopefully it's a bit clearer now.
If possible please provide the links to the giveaways (most of you are doing this already). I know the search function here sucks, but it would be useful to be able to see the giveaway you're talking about.
Also, please make sure you mark clearly the giveaways you're nominating and the ones you'd just like to mention. I know 3 is not enough, but if I don't make this limit, we'd probably end up with enormous lists. So, you have to make a choice about which ones to pick for nominations.
Don't be afraid to pick giveaways which you subjectively like for personal reasons.
helpo1: Esoteric Challenge (Giveaway) by ZFR (I'd nominate this one, but ZFR would probably decline it. :D)
Thanks! But you're right, I can't pick myself. Should by any chance a post nominating me win, the nominator will still get their prize, but I'll choose another host to replace me for the 9.99$ game.
