I fear chadz is right on that subject.
Nonetheless an announcement that you are looking for (good!) coders could change something, perhaps. I know the chances are small, but if you mention that cRPG needs coders or it will die a cruel, slow death, some people, who would be willing basically, but just thought "People are already working on that mod, they don't really need my help so I have more time for climbing/cycling/gaming/picking up/watching porn." would change their mind, and dedicate themselves to it.
I know it's not very likely to have one or even more persons with exactly that attitude, but the try won't cost you anything more than a few minutes for writing the topic.
Yet another advice I have would be to release something which changes the feel of the game as radically as possible, for example changing the multiplier system or implementing a new game mode. This is a change you would have to do on your own, but once implemented, people get the feeling there's movement again, the game becomes "new" again, older players who left become curious and join again, and the overall amazement (?) raises again. This is a good moment to look for motivated people, who can relieve you a bit.
