Ive seen a new site pop up by a few campaigns called kickbooster that is supposed to help you engage your current backers and help them spread the word about your campaign.
Yeah, I've been getting some news about them. You're only supposed to sign up once your campaign has launched though, so I don't have any firsthand experience. I'll let you guys know more after October 3rd, when my newest comedy/sci-fi launches. So far I plan to go with them.
I confused BackerHack with BackerHacker, which is another Crowdfunding site. No so keen on the name as "hack" isn't the most trustworthy name you could use

I have added our Campaign for our Scifi Animated Series to backerClub.co. I will give my POV after our campaign has finished, Hopefully that can give some insight to their process and their Worth.
Who knows I might get Burned, but luckily i have budgeted for that.
