I could quite possibly be interested in this. I was born for writing in great detail what is going on in my character's head.
I won't make any promises as to whether or not I will join, though, since I need to see how a few other arrangements go first. I will be following it, though.

Great idea, Strawberry!

PS
My younger brother was actually supposed to be a twin, but the other one died in the womb, so I might just be using him as a loose basis for character creation, should I have the possibilities of joining.
