Has anyone considered Reddit. Feel this would be a good way to have some targeted publicity. Subreddits like r/nba has 380k users, r/Games has 690k users, r/gamingsuggestions has 18k users, the biggest is r/gaming with 10.4 million users. Being able to get on the front page of these reddits would generate free advertising.
If we could organise a few hundred BB players to upvote each post we could maybe get a good return from it.
