Writely.com

Writely.com, which is currently free, is pretty much Microsoft Word on the Web. This means that you can use it to write word documents which you then save to writely. These can be accessed by you or anyone you wish to allow to see from any computer, because it's on the Web. You can also work with someone else on these documents, together, simultaneously even. I encourage one and all to set up a (free) account as soon as possible.
