I couldn't pull it through with our available extensions, as our posts need to be locked for privacy reasons, so the content didn't come through.

I know there's a WordPress for Joomla extension, but couldn't tell whether it would work with copying over a pre-existing blog, and I saw the WordBridge extension, but wasn't sure whether that would work, given the locked content.

Basically, I'm wondering if it's possible to either a)have the content published over in a way that feeds the password through, or b)lock the page on the wordpress.com side, taking the passwords off the posts themselves, and allow it to feed through that way.
