I'm afraid I wouldn't have the time to contribute content, but I will be around to answer any questions for potential new scenario designers. There just aren't enough of them around here.
Scenario design can seem like a daunting task, but if you are shown the proper methods, shortcuts, things to avoid, etc., you can start shelling them out relatively quickly. The research is what is the most time consuming, but it's also the most enjoyable part, at least for me.
Again, if anyone has any interest in it, myself and I'm sure RebBugler, will be around to answer any questions you have.
