I like the idea, though I think you'd probably have to get it up and running to see if it works, if that makes sense *g*

As long as it was easy and simple to use for both readers and writers, I can only see it doing good - it would take the worry away from authors that they're going to under-warn or over-spoil, and readers wouldn't have to risk being spoiled inadvertently. Sounds like all round win *g*
