Livejournal Sold to Six Apart

I know this could have gone in either Cool Sites or News, but I figured more people would read it here and my question would best suit Chit Chat.

I know that they say that Lj will be the same and all that, but I've got 4 years of memories written in that thing. How do you back it up? I'm super clueless about any of those programs and things, and I don't wana somehow end up losing all of it. Thanks!
