You really need to be active around here and other spaces. That's how you grow a brand. I checked through your site and noticed that there are some promotions and tournaments, but the audience is lacking.
I am glad I joined your St Patrick's tournament today, which ended in a rather spectacular way. If it wasn't for other members bumping up this thread, I wouldn't have known.

Please consider having some of these slot tournaments or contests promoted in boards like Games and rounds for more exposure. Look through the board and see how they try to promote them.
People like @Little Mouse are really so got at managing such contests if you find it challenging, though the minimum bet limits may have to be reduced a bit. It seems so many members are scared of making a bet of $1
