Re: Hack: bb replies as wp comments; using bb API?
You do need to use that table, but if you installed WP yourself it should also be created when you activate the plugin. Maybe de-activate and re-activate.
However I’m working on a plugin that will do the entire thing (complete integration hopefully) based on a different, IMO much neater system. I don’t want to promise anything before it’s done, but if this plugin doesn’t work for you there’ll be a simpler alternative soon.
