I tried to make a trackback from a Windows Live Space blog to my blog on WordPress.com. And nothing happened...
I gave the URL http://<myblog>.wordpress.com/<theDate>/<nameOfThePost>/trackback/ as the URL for the trackback. I already trackedbacked within my blog with the same address and it works without any problem. More interesting trackbacks from WordPress.com to Windows Live Space are working.
Does someone have the same problem? If yes, did you find some solution to it? Did I miss something?
PS: my blog on WordPress.com is not private and the blog on Windows Live Space neither.
