Whilst I would love it if you never went to any other site other than this one, I think that's a little needy of me, so why not explore these sites if you've nothing better to do...

As suited to my way of working Movie Draft is, it may not be to yours, but don't worry, there's plenty of other software out there to choose from.
A great tool for writing novels, technical documents or even screenplays! Scrivener is a vast application and shares the same non-linear ethos as Movie Draft. It is well thought-out and Keith, the developer is a great guy to boot. Well worth a look.
Celtx is a fully-featured screenplay and production organizational tool, and for the price (it's free!) you just can't beat it. For me personally, it just doesn't "feel" right on an aesthetic level. Maybe that's not important to you in which case give it a whirl - it won't cost you a penny.
- Final Draft
Now in its 8th incarnation, Final Draft is the industry standard in screenwriting. It's been around the longest but does tend to have a love/hate relationship with its users.
- Movie Magic Screenwriter
Screenwriter is currently in 2nd place to Final Draft in the screenwriting software popularity contest. It can do everything that Final Draft can, but does it in a different way. I've personally never gotten on with either of them (which is of course why I wrote Movie Draft) but that's not to say that you won't.
If you would like to share a link on here, drop me a line and I'll take a look at it.
