Really simple, formats it for you.

I tried to use it last year and it was all going swimmingly - and then midway through April it stopped being able to save my script - i'm guessing the website got a little bogged down by all the scriptwriters using it - :(

So I went back to celtx.

Well, I tried it, and it is very good for a script site, but unfortunately you can only save it onto your computer as a PDF file. I couldn't even add a comment... It was kind of weird. Celtx, I'd say, is very good... it's what I use, and what I'd recommend for Script Frenzy. Though, if you can't download anything, Scripped is probably your best bet. :)

This is my first time writing anything (aaaaargh!) and I decided to go with Scripped but with what you've said, I'm curious about CeltX. Maybe I should give that a go..?
