This is a good idea. There are probably many things that could stimulate the players to attract attention to Graal, possibly setting up a gralats-per-subscription when you advertise a link, be it a banner or text, in your signatures in other forums or on personal websites.

As displayed by iPhone Graal's success, I think it's probably best to revert to advertising and marketing Graal as an actual game aswell.
