SOFTWARE
Final Draft
Yes, there are other software packages out there, but Final
Draft is pretty much the standard.
You can even exchange Final Draft files between Macs and
that other kind of computer that I will refrain from naming
(the one run by software from Redmond that gets all the
viruses, spyware, and is a total pain in the ass to use).

Screenwriter's Initial Draft Pad
Although this is not software, it seems appropriate to
mention it in this section, since it is a tool for writing
and a temporary substitute for script software.
I hate writing by hand, but on the rare occasion that I
need to do it, this pad is amazing. It has light blue lines
on it to help you format a handwritten script. Then when
you photocopy the pages, the blue lines disappear.
You can also get these pads at the Writers Store.
