I remembered Durnominator's suggestion about using a gaming hub to recruit. Seems like a fantastic idea - so I found the information for MMO developers on Kongregate's website (but there are other categories of developers if CF would fit better elsewhere)

Kongregate is an extremely popular gaming hub - 55,000 people are online right now. Please think about it!
