@Peter: unfortunately I have to confirm the authorizing issue – failure to add the key to the url, landing on the “woah there” page about the token already being used …!?
My environment: PHP 5.1.4-Debian-0.1~sarge1, CURL support enabled (libcurl/7.13.2 OpenSSL/0.9.7e zlib/1.2.2 libidn/0.5.13), WPMU 2.9.2, BP 188.8.131.52
… is there a way to do authorization manually? How should an uri with “authorize?oauth_token=” look like?
