I have the Vimeo iPhone app on my iPhone. It seems that you can upload movies directly from the app to my blog. I have a .nu domain for my blog, and not a xxxx.wordpress.com blog.
I have trouble accessing the blog from the Vimeo app, as I'm not sure what username / password / URL to put into the fields. URL example is "myblog.wordpress.com", but since I have a .nu domain, could it be this that prohibits me from accessing it?
Hope this makes sense for you.
