Mozilla Inline Editor is an in-browser, context-sensitive, XHTML editor that allows a user to edit all or just specific editable sections of any XHTML page from the comfort of his own browser. It can act as the client-side of a content-editing system or as a self-contained "web word processor".
Tom Hoffman pointed to this the other day. For those of you who use Internet Explorer on the PC, this is not a big deal, but for anyone who uses another browser on the PC, or uses a Mac to publish their weblog, Mozile is a great add-on for those looking for a simple html editor.
