The first tool that I would like to share is a very powerful one. Working on Word or Office documents in multiple places can be quite challenging. One computer might have the program and another might not. The versions may be different or a host of other issues can cause it to be very difficult. ThinkFree.com, Writely.com*, and zohowriter.com are all web based "Word-like" word processors. They look very similar and function almost exactly the same as Word. In some cases, they even have some more features if you are using an older version of Word. These tools can be very powerful for the whole writing process as well because they allow multiple people to work on the same document. You can collaborate, edit, and share very easily. If you have access to the internet you can create, open, and save your documents even if you do not have Word on that computer. Click the links below. Each site will have a tour of their offerings.
* Writely
*Update: Writely.com was purchased by Google a while back and it is now part of Google's docs & spreadsheets. This is great because now you have word processing and spreadsheets in one online tool.
