A repost is typically classified as such because it was posted in a Forum that had been archived. (one that can only recieve replies, and no longer posts)
Once it's been archived, then you can select a poem to place in any forum (fitting of course) for a repost.
But if you're taking a poem from an open running forum and placing it another open running forum, that is considered double posting, or cross posting. That is strongly discouraged, as it uses up bandwidth.
If this is the case, (it's in an open forum), you might want to contact the Moderator of the forum you originally posted it in, and ask them to move it to the forum you'd like it in.
