Thank you.  Its because people like you test this out on different
platforms that I can continue to improve weblogger.el and xml-rpc.el.

I note that the Windows Live weblogs have RSD headers that specify MetaWeblog.  
The best way
would be to use RSD to determine what to do with a particular weblog.
Right now, it uses a MT-native call (mt.supportedMethods) to see what is
supported.  Obviously, if you implment MetaWeblog but mt, this will

Because of that, I'm not going to use the patch to weblogger.el.  But it
is clear that RSD should be my first priority for weblogger.el.

If you would like to try to tackle it (since I'm not sure when I will be
able to), I could help you out.

Thanks for point this out.  Obviously I didn't test that.

Ok, I'm going to assume this is working and I'll use your patch here.

Hrm… I'm not sure about this.  It'll take some testing.

This is probably a short-coming of Emacs HTTP support and this isn't the
right place to fix the problem.

Thanks for your contributions and putting effort into tracking this
