I have used the promotion deal, it helps to get it out there some but best way to get people involved I have found is by making connections out there by following like minds, chatting and making friends through comment conversations genuinely and the next thing you know you have a bunch of friends and backers for your posts. This only works through the community aspect the most, making real connections goes a long way for yourself and others. Can be a daunting task but well worth the efforts if you have the time to do so.
