Does the twitter functionality only work when posting the field notes via SMS through TextMarks (not available in Germany) or using the iPhone application ?
I've uploaded my founds via the the "upload your field notes file" form (http://www.geocaching.com/my/uploadfieldnotes.aspx), the field notes where saved correctly, but no updates were sent to twitter. Of course I saved the correct twitter username and password and checked the "Post to Twitter" box.
Thanks !
