I'd like to edit text together with someone, either using Windows live messenger or using a website. Is there any site that makes this as easy as possible to do so:
No registration. just an identifier to return to it later. We have enough accounts.
Live updates when text is updated, i want to work on the same document 'live': no having to reload it to see changes, and in the same window not like chatting.
A way to save it and return to it later as the document will require multiple sessions of collaboration.
I need to get the information out in text editable form afterwards.
Anything else is optional. But I can't find anything looking for
http://text editing collaboration. Can you help?
