Would be excellent if you could import.....
Yes, look through it and you'll see "Import" but that's wrong and relates to English as a second language (I assume). "Import" allows you to "export" BF articles to make them regular Joomla articles (guess it has some use). But there is no way to really import anything into BF.
So, if you have an existing site, with many posts, be prepared to manually add every post to BF to make it functional. IMHO, this is a fatal flaw. I asked about import and was told "...it's not implemented in this version..." No thank you, no "we're looking into it", no "gee, that's a good idea".
Having said that, for a new site or a revamp of one which doesn't have a blog, BF would be a great component. Powerful features and reasonably intuitive even without reading the dox. If they put in a proper import of Joomla articles I would give it 5 stars.
