I'm afraid I can't tell you Dave.
Shouldn't the developer have written an entire platform for this? Nemesisbook. That way we have a single place to manage all of our nemesis'... nemesisis...nemenemenas...
For example, we may want to track their movements, plan and execute practicle jokes, instead of "poking" we would "mock"... for everything that you can do on Facebook we would want its opposite on Nemesisbook.
Clearly this guy doesn't think big enough so he is my first nemesis entry.
