Sometimes we 'oldies' even want to see a repost. The only way I know is to search the archives and then email the individual poet, ask them to consider reposting. you won't be able to re-post someone else's as far as I know, except perhaps to highlight a link. My understanding is that once a forum is closed, you can post a reply but only the author can 'bump' it back into an open forum, by re-posting. But it's always a good idea to ask a moderator for help.
