Offline blogging

I am writing this to find out if I can blog offline. I am aware of the feature which allows one to send email to the registered email account which in turn forwards it to the blog however now I have blog applet and I am interested in posting multiple blogs and see how they appear on the web site. This thought took genesis today when I was posting another post and an old post showed up which yet hadn't been plaster and when I published it, it appeared before an already published post.
