Writers' Blocks

This is a story built block by block rather than the "I'm stuck" kind of writer's block.

At their website RIF (Reading Is Fundamental) posts the beginning of a story each month at Writers' Blocks and anyone who wants to can contribute to it. It stays up for a week then then the final story is posted.

The next story begins April 2.

The past stories are all at Previous Writers' Blocks. They all seem to have contemporary settings with some fantastical twist to them.

I haven't seen it in action so I don't know how they handle multiple entries for the next block or how they notify writers that the next block needs to be a wrap up. Each story ends up with five blocks in addition to the story starter.
