A lovely idea, but it can take 1-2 years to get the art and writing and programming together for a plot (we have to do it in between the usual art that the site needs!)

We've been having a think about SOMETHING happening, but nothing quite so big as a plot!

[Edit]

Oh whoops, I had this tab open for a while and was only replying to the first post. I like some of the ideas in here! I actually do have a little idea of what to do actually.
