As far as I'm aware there isn't a working mod for 3.0 or an extension for 3.1 (have a search) available here. Have a look on the Wordpress site, there used to be a bridge for 3.0 and, if you upgrade to 3.1, there's
BridgeDD PRO, it isn't free though. Incidentally, you don't appear to have a phpBB board running so, if you intend installing phpBB, you should install the
latest version 3.1.9.
