struggling to write a call

I am trying to write an open call for art/games to show in the upcoming game curatorial I am working on with JP Bruneau and the Euphrat.

What we know is that anyone can make games and that there is no way we can find them all, so what we want is people to nominate their work or their friends work for the show.

I am expecting the call to go out pretty widely as that is really the only way that it can succeed and that is why I am struggling over it.  The words need to reach a variety of people and motivate them to put their work out there. It is an interesting challenge and begets another which is to sift through all of the work submitted.

Additionally we have to say how we want work submitted.

We have about a month (6 weeks) to collect and sift through the work.
