What is yWriter?
You can download yWriter from the Spacejock Software yWriter page.
Why all the different yWriter sites?
The main website discusses yWriter features, allows you to download the program, and contains information about updates.
The yWriter group is a mailing list where you can ask questions, exchange tips and information on the program, search for answers and interact with fellow users and writers.
The yWriter Wiki (the site you're looking at now) was set up so that any user can contribute to documentation for the project. FAQs, Guides, assistance with updating or restoring from backups - eventually these pages will contain a rich source of information for all users.
If you're interested in contributing to the documentation project, please see the Contributors Page
