I'm really not sure how this will work for you, but I got the idea from my friends group on facebook.. Basically its a group of friends that do a quick sketch each day.

rules

1. its a sketch not a full drawing. all you need is a few minutes a day. most are about 15-20 min sketches.
2. there is no erasing. grab a pen or marker. Pencil will do if you don't erase. mixed is ok too
3. everyday the topic changes.

My Idea is to set up the page like a forum/ gallery. Each day a random topic could come up. maybe a random generator or someone could pick. People would read and post their sketch for the day there.

or maybe someone can make a Paper Demon Group and we can do it there.
