I recently switched this blog to
dasBlog and I had a nice little firefox addon called ScibeFire that I could not get to work with it. Thanks to
Kelly Keeton for the tip that made the connection in my head.
My confusion was the end point on
dasBlog is called Blogger.aspx, but the type (API) is MetaBlogAPI, so when setting up the blog in ScibeFire you have to choose Manually Configure-->Custom Blog-->MetaBlog API then put in <%yourBlogPath%>/blogger.aspx.
Then it works great. In fact, this is my first post from ScribeFire.
Edit: The only problem is ScribeFire appends an ad to your post. To disable the add/trackback, click the ">>" in the upper left, choose "Settings" and uncheck "Automatically insert' Powered by ScibeFire'"
