Not Sure if this could be a good idea but here it goes.
If I'm not wrong this is s Rolepley server.
Then perhaps could be more easy to atract gamers from other kind of rolepley games like board games or non space rolepleying pc games to a Spece roleplaying game like freelancer than combat/space gemers to RP space game.
I'm saying this to not focus on "traditional" space game forums or wherever the add has benn send in the past.
Where to search such gamers? Uh, dunno :S I'll give it a try at google...
Just a thoguht.
Edit: Just found some RPG forums where perhaps could be interesting to write a post
