A thought

There are MILLIONS of private giveaway groups...

It's a new year, what could go wrong.

This idea has been shared (and acted upon) by many others before you. Feel free to follow their example. )

As others have said, people have already done this before but you might still feel inclined to make one yourself. A group for contributors does seem a bit pointless though when you could just set the CV on your giveaways, unless you want the group to be more of a social environment and not just about giveaways. Try to make it your own though or otherwise unique. I've considered making a group for everyone I've won something from or ninja'd a key from (or just generally awesome people from the forums). However, I don't have tons of things to give away thus far, so I'm waiting to make that group.
