Plotty plot? I don't have any suggestions thus far...
Except that I think depending on the scale of the plot we go with (so if it's big or small, the plot might be confined to multiple regions or smaller) the amount of people that can participate in the plot will change too?
Uh, I'd have a suggestion as to what kind of plot I'd like the forum to run with for a while, but I have a headache. .-.
