I have to move from WP to MT my blog. I think WP is best open source blog platform but it's for specific reasons, which I won't explain here, that I need to migrate to MovableType. I don't find such feature on WP. I think it should be useful even for having multiple syncronized copies of a blog on different platforms. In example w.bloggar client allows syncronized posting on multiple blogging platforms, even if WP will be really supported only from version 4.0. Thanks in advance.
