It is a simple way to create a page which can be shared with anyone.
There's no need to login. Simply start a blank page by click on the justWords name top-left, and start typing.
As soon as you save it, your page is live. The web address to the page is on your browser address bar, or under the 'info' option top-right of the page.
If you want to edit the page in the future, make sure to set a password under the info menu option.
