Okay, here's my proposal, which has three parts:
1. Make an effort to PM and otherwise contact Nuru and Helen through means that we have outside of BD to request their participation.
2. Determine what is the most likely course of action for Nuru and Helen, and based on this consensus, move forward with the thread.
3. Plan on Helen and Nuru writing catch-up posts to fill in the plot over which we have passed in order to keep things going.
So by way of summary, the time that it takes for us to reach a consensus as to what Nuru and Helen are likely to write regarding Leafa and Mellonin respectively, is the time we are giving them to post themselves, and if they don't post by the time we have reached a consensus, then we move forward and ask them to fill in later.
All in favor, put forward your idea of what you think Leafa and Mellonin are most likely to do.
All not in favor, please say so.
Or tell me to be quiet and wait.
