Free digital copy of "Are You Dreaming?" you say? That's quite awesome! Don't see how one could pass that up

I posted about it on some Google+ communities and contacted some people in the LD community that have a pretty decent following on Twitter/Youtube to see if they could help spread the word. Hopefully they do and it creates a ripple effect, and gets some more backers for it

Also, have you tried posting about it on some kickstarter/crowdfunding communities? Such as r/kickstarter on reddit? r/kickstarter looks like they don't allow asking for backers, but sharing the campaign on there and similar communities could help get the word out more.
