Any ideas on getting steam members to join your raffle/giveaway/trading group?

Create giveaways for that group only? :)

• Be someone who has done giveaways.
• Don't ever do raffles or admit to doing raffles, for some reason asking people to give you stuff is frowned upon here and gets you blacklisted rather that group members. :P

So basically, do stuff that makes you look like a good person, rather than a beggar.

Another stupid group trying to make profit out of raffling CS:GO items. All I can hope is that your group doesn't work out, not like we need any more of these groups.

Another guy trying to make profit from us, great.

My advice: Don't use "Invite all your friends and win ____ contests". Everybody hates that.
