Well I'm now testdriving Fedora, still have to used to this. So I first just looked at "software center" and there was no aspell-fi. But just tested via commandline and it seems to be there, but... If I'm not wrong all spelling efforts have been put to voikko for years now. I don't know that any distro uses nothing else than voikko as default for Finnish. But then again as said, this whole thing is so new to me that might be more than possible that someone else has to do this at the end, but until that I can give this a try and study things when I have some time.
