How are you using social media to promote your forum? It can work really well but only if utilized correctly. I see you only have 13 posts on FP- it will help if you stick around longer and use our post exchange, forum cash exchange, and package service sections. Those things in particular will give your forum a boost. Forums aren't an overnight get big thing, you will need to spend a lot of time on them and have patience/dedication. Try referring family and friends to your forum as well.
I'd recommend you make a decent graphics to wear in your signature. Whenever you do that, something as simple as posting on a forum (while a banner is linking to your forum), can help you advertise to gain users.
