IntelligeN 2009 can post to any WordPress website through the xmlrpc. But it cannot crawl/fetch a forum threads content. However you can copy and paste the content, that needs to be submitted manually, or i can build (in cooperation with Hyperz) a plugin for IntelligeN that gets the content automatically.
But i don't know how flexible SharpLeech is, because the plugin will start a module from SharpLeech that will only read the content of the thread. But i need a "special" api from this program and the permission to do this.

Furthermore i can write a plugin that will do the job of SharpLeech (crawl/fetch a forum threads content), but this is not gratis.
