I have not been able to use this app at all, as iWeb Extender cannot find where to place the files on my .Mac iDisk. I tried the "publish to folder" option in iWeb first, and then drag and dropping the files into that folder, but the blog files were named differently.
The GUI overall looks very nice, but the documentation needs to be fixed in a large way. I can't use an app if either iWeb Extender can't find where to put the files or at least tell me where to put them (the help documentation doesn't specify).
