2006-12-21 Update: Writely is now part of Google, which provides both word processor and spreadsheet.
While surfing the web, I stumbled across www.writely.com, an online word processor that permit collaboration, i.e. many people can simultaneously edit the same document.
Sign up to the service is easy: all you have to do is entering the email address twice and supplying a new password; it takes less than one minute. Inviting other people to collaborate your document is easy: just click “Collaborate” and add your collaborators’ email addresses. The invitees will receive an email notification with the login URL, and the password.
Writely also associate a unique email address to each account (email in). The user can send document to this email address.
Pros
- Fast, easy to use
- WYSIWYG editor
- Email in feature
Cons
- No spell checker
- Flat folder structure, better to have hierarchical folder structure.
