What do you use?

[V.W.]

Libreoffice, and Zim Desktop Wiki for all the planning, research and character layouts.

[Pavan]

I have been looking at some of the ones that I have never heard off to see which one might work best for me x

[Erin]

OpenOffice and now Scrivener as well.

[Neil]

Like others, I use Word set up with Styles for Headings and Normal so that Table of Contents can be generated once the final version is ready. This is saved as default template so I have no need to repeat any procedures.

[Edward]

I tend to use coffee in the morning and cheap rum at night.

[Denae]

I've heard a lot about Scrivener but haven't looked into it yet. Hmm.

Right now, I use notebook to Word and edit/draft/format everything from there.
I had not thought of using Excel except to keep track of the royal family tree. I should use it for outlining. *facepalm* Why do these brilliant ideas seem so obvious in retrospect?

Lolz! Switch that rum to a Tom Collins and that's my typical day dealing with multiple systems for one book...
