I tried to do some basic stuff to my empeg lately (fsck, mp3tofid, etc) and searched this forum. All "useful" replies point to riocar.org. I was able to do everything I wanted, but it was much more complicated without the FAQ.

I don't have any experience with wget other than what I can find with google. But it seems it shouldn't be that hard if you still have a running "private" copy of the website.
