Mozilla Etherpad
Etherpad is a collaborative editing tool hosted by Mozilla. It is useful for co-operative document creation and editing, but should not be used as a long-term storage solution.
Documents created in an Etherpad are temporary. If you need the text in an etherpad to be available at a later date, please put a copy of it in Mana, WikiMo or a Google Doc.

This is a public pad, so be careful what you put up there!
