Scripto does not yet have title page functionality but it's easy to add a title page to the PDF of your script using Preview (on a Mac) or Adobe Acrobat.
Here's how you can add a title page to your script for distribution:
Export your script from Scripto as a PDF.
Open a word processing program and make your title page. (Here are some details on what a screenplay title page should look like.)
Export your title page as a PDF.
Open your script PDF in a document viewer like Preview or Adobe Acrobat.
Add the title page PDF to the script PDF and save. Your script PDF now has a title page.
If you aren't sure how to combine PDFs in Preview, here are instructions.
