Hi Stephen

I just learned about this software, Celtx. It isn't an outliner or a PIM, and
it is designed for screenwriters and dramatists. But it seems packed with great
features, and seems to be well thought out. And it appears to be free.

It is not only free it is also Open Source. And it's available for Windows and the Mac.

I do not use it as I do not write screenplays.

Celtx has been mentioned several times in the Scrivener forum. 2 threads might be interesting for you.

One on an older version of Celtx:

And another one discussing how to import Scrivener files into Celtx:

Hope it helps,

Franz
