One way to not have much trouble (especially technical crap) is perhaps to not make it as a game.
I kinda like the idea where each of us have our own character(s) continuing a "never-ending" story. Perhaps everyday(or week), one randomly picked person will be the GM, and decides a "plot device" to lead the story for everyone else to continue (writing about).
Plot devices can be anything. For example, "Locate the hidden treasure/entrance/exit..." to something like "You have 24 hours to do something something, or else something something...".
Others who aren't the GM during the period, will have to write (and post) the story/journal on how their character(s) proceed along the plot. Maybe you want them to succeed, fail, or not even bother with it?
Problems we might face?:
Might have to think more on how to make sure it doesn't get "messy", since there isn't any link to each of our characters. I may have my character go kill a pot for eg. while someone else simply sleeps, under the same plot device.
Also, once it's time to decide a new plot device, we could perhaps rate each other and give EXP/rewards for how we dealt with the scenario.
tl;dr --> think of it like a progressive community fanfic story/journal, where each of us will decide the "plot of the day (week)" to write about. Everyone's the GM.
[hide]Pretty busy at the moment actually. But kinda "burned" out to continue thinking/writing my report, and instead thought of this ._. [/hide]
