On iScribble.net, we have this little thing where users take turns having characters interact called an "Image Roleplay" - Basically this is a very good practice for learning to draw a character in different situations/poses/actions/interactions, and for practicing to imitate them as closely as possible to their personality.
Drawings are usually very minimal to their base structure, though sometimes more detail is put into more 'static' images where only arms/facial expressions are changed, usually if they are just conversing.
Props are often used, objects of interest are drawn for scenery (Anything else just causes clutter)
At this time, roleplay seems to be banned from iScribble, but IS allowed in private boards.
Give it a shot, and if you want to save the whole thing for review later, thinking it may actually make for a good episode, just save a screen shot after every turn to combine it into a comic later.
