Help me increase giveaway limit.

You start with 3 slots and for every 3 giveaways marked as received you gain an additional slot, so create some more giveaways? If you have a bunch of games to give away, in the past 2 weeks you probably could of got your account to over 50 giveaways slots with short running giveaways.

If you are specifically looking to create 1 high quantity giveaway or a long train, then I guess you will have to wait for the support ticket to be answered. I'm not sure who has the ability to increase giveaways slots, but there are not many support members on the site and they have a lot of stuff to deal with, so tickets can sometimes take a long time to get to. Plus, it's the holiday season and people are busy, so the few people that process tickets are probably spending even less time than normal on here.
