Sorry this is coming in so late: I just got approved to post to this
list last night.

So, influenced by the "start at any time" spirit of 24 Hour RPG, I
convinced a few friends to all make their own RPGs in a format similar
to Game Chef. Somehow, I got motivated enough to make a dedicated site
for it. Visit us at http://summer2008rpgchallenge.ning.com/

The "Secret Ingredient" was just revealed today around noon, and
submissions are due by 11:59PM on Saturday, August 2nd, just to give
you an idea of the time-frame.

Take care everyone!
