My friend and I are building a CMS specifically designed for online roleplaying. For the playtest we are using it to run a superheroes-themed game. We've built in-site tools to help making posting and character creation easier, and we're continually working on it based on playtester feedback.
Right now we have a few playtesters helping us to test the system, but they're all people we know — we have no experience with folks who are unfamiliar with our system and how we are doing things.
How do we attract folks to be playtesters for our game/platform ?
