Thanks AN-net!
Funny enough, after failing on installing this, we tried exactly that hack!
I was hesitant to use that one, because I had already written an importer for the Antonbomb22 journals from our old journals script and I was devastated to see that 3.5.0 came out
Then I found out that the 3.5.0 hack was based on Antonbomb22 and used (almost exactly) the same database layout, which saved me a LOT of work recreating an importer!
Kudos for the developers and maintainers of this hack!
