I used to play this on a forum a long time ago so, why not start anew? To do this people sign up (Lets say... 12 people for this) and then I send the first frame of this 13 frame comic to the first person to sign up, then once done s/he sends the second frame to me and the second person. the second person makes a frame and sends it to me and the third person etc. etc. so each person only sees the frame before it.
So, essentially, I draw frame one, someone draws frame 2 and sends it to me (so I have it) and to the second person on the list. The second person draws frame three and sends it to me and to the fourth person on the list (they ONLY send the frame that they drew)
