Why?
Scripts are allowed in FF&W so long as they are written well and actually look like a script to a play/show/what have you. The thing is, though, is that there aren't enough of them to warrant an entire subforum dedicated to them. If scripts took over FF&W and people wanted them to have their own section because it proves that it needs one, then it'll get one. But in all my years here, I've only seen maybe two script fics that weren't closed because it followed the rules of script writing.
Unfortunately, two fics won't be enough to dedicate an entire subforum to scripts. But you can still post whichever ones you have written in the main forum of FF&W.
And this is bothering me, but isn't play scripts two words? Unless you're talking about the publisher, of course.
