Submit portable freeware that you find here. It helps if you include information like description, extraction instruction, Unicode support, whether it writes to the registry, and so on.
Portable Celtx is a free, open source software tool for writing and formatting a screenplay to meet the exacting screenplay submission standards set by the theater and film industries. It provides support for the entire pre-production process.
I feel this is a quality bit of software. No use to me at my age but I suspect many will find it invaluable.
As per my comment in main site:
a new stealthy version of Celtx (2.9.1) is available on winPenPack site
as usual, the name with portability appearer integration is X-Celtx http://www.winpenpack.com/en/download.php?view.759
hope this helps!
The "Overview" page referenced above is busted. From the about page:
Our mission is to produce engaging, standards based software for the production of film, video, theatre, animation, radio and new media. Celtx is the result - the world's first complete, end-to-end solution for media production and collaboration.
Old topic update: OP portable download link is dead.
BTW, CeltX still has a freeware version, but appears to have gone payware (although keeping moderate prices for the genre, see http://www.celtx.com/services.html); moreover, even the free version requires registration, and plugins are mostly for pay (there's a version comparison matrix at https://www.celtx.com/a/ux/desktop#desk ... -container, but it too requires loging in).
