-Wordpress Plugin to avoid double postings-
I am building up a wordpress-blog with several authors - So they can register and post an article by a form - I use TDO MIniforms plugin!!! - and the solution should be used as a hacked form oder as a plugin.
Now here we go and that's important: i want the author to show if there is already an article/ a posting with the entered url in the custom-field. and i want to show them a tooltip/balloon/message (and maybe redirect them to the posting/article).
i only want to avoid that my authors are going to post several articles to the same source (indicated by the url).
