SharpMT is an offline Blog writer that is designed for MovableType based systems and TypePad hosted blogs. It allows a writer to write a new Blog entry on an offline computer and later upload it to your server with one click. SharpMT can also syncronize the list of categories and a cache of previously published posts that are already on the server, offering automated cross-entries links. The 3.0 Beta 2 release adds support for initial bookmarklet integration.
