A place to store your writing?

If you go to www.freefilehosting.com, you will find a list of file-hosting websites, along with user reviews, storage limits, whether or not you have to sign up to use it, what types of files are allowed, etc. It's a good place to find websites to do exactly what you want to do--back up your files on the Internet, where they cannot be found unless you, yourself, give someone the link.

If you don't have one already, register for a Google account. Along with their email service (which I couldn't live without), the account gives you access to Google Docs, which is exactly what I think you're looking for. It stores documents, spreadsheets, and other file types, as well as allowing you to access and edit them right on the site. There's also a number of other tools, such as Google Notebooks, that may be of help.

I store novel-length fiction in my Yahoo! email account. I just email it to myself as an attachment. Then if something happens to my computer, or my home which includes the computer and any back-up copies I might have in whatever form(s), it's still sitting waiting in my email.

When Yahoo says unlimited storage, I take them at their word.

I'm not sure, but I starred this question because I would like to know too :-)
