Best way to recruit playtesters?

[The Hound]

Our site (rpgtonight) is in need of 10 GMs and 50++ players to playtest on online tabletop style "living game" starting in March. I've just started posting notices on the major boards like this one, mostly in the games/gamers wanted sections, and we have a collection of people from our own site. But I am wondering if anyone with experience at this knows what the best way to recruit lots of playtesters is. Does it ever come down to having to pay people?

That's a good question. I've had some luck just posting to forums -- but, as you'd expect, reliability of those playtesters has varied widely.

Looking at the forums here, I'm not even sure which forum would be the appropriate one to post in for a call for playtesters.
