As the subject line suggests, I cannot submit a post to Playlist Exchange with linked playlist. When I click "start a topic" and type in subject, message and link to playlist, and then click the I'm not a robot thing...I do not get a "post" button. When I click to "preview post" I get an "unexpected error" message. Just to mention, but the "post" button is not there from the moment I press start a topic.
