I run a forum with 3500+members and 160,000+posts. I am looking to do a giveaway based on the niche we are in. In the past with giveaways I usually do it in that you have to register on the forum, then post in a thread which acts as your entry. I am looking to maximize members & earnings for such a giveaway so I was wondering if anyone had a better system of operating such a giveaway? I also am looking for long term growth...i.e members who join and stay. I am planning on promoting the giveaway on facebook through ads and online. Any ideas are appreciated! Thanks.
