I stumbled upon your blog: http://developernotes.thomaspowell.com
What I noticed – and it's something that I wanted also – is that your blogpages are all ending in .php, even your individual blogpost pages (http://developernotes.thomaspowell.com/2008/10/remember-milk-is-on-twitter.php)
How do you do that in settings? I can only get the index page to end as PHP. The individual posts remain in HTML.
Could you share this nugget of wisdom with me?
(Note: I've only done this publishing to another host via FTP)
In Blogger dashboard, click the [Settings] link for your blog.
Under the [Settings] Tab -> [Publishing] Tab, edit the Blog Filename field. (index.html -> index.php)
There is also a setting for the archive file:
Under the [Settings] Tab -> [Archive] Tab, edit the Archive filename field. (archive.html -> archive.php)
One more thing to note… all the old *.html files will still be left on the server, so if you want them removed, you'll have to clean them yourself.
