Below I present some sugestions.
I had an idea for a big party at FH. It would be official, advertised on tweeter, Instagram, Youtube, Tumblr, DeviantArt and Facebook. I pay special attention to Facebook. This social network is the most popular. So why doesn't anyone run an official fanpage? The site itself exists, but the post was strong around 2012. So I think that if we re-launch the fanpage, we may have a better chance of greeting new faces.
Returning to the party: there would be radio, competitions, help for novices (this event would be mainly for novices, so well) and many other attractions.
What's more, I've noticed that there aren't do many new YouTube videos about Feral Heart. I mean unofficial game download tutorials, roleplay recordings etc. I would like to advertise the game myself, but I mustn't have channel on YouTube. Of course, thank you to every forum user who advertises the game, but so far it has not done much.
I know that these are small suggestions and probably repeated many times (if they were repeated frequently, I am sorry), but they seem good to me.
