I have created an archive of the MJ forum and the Thriller 25 forum of MJNO.
It's from January - a few days before the forum closed.
It's got a size of over 400MB when unpacked, but the actual download is only 115MB.
Anyone who wants a copy, please PM me.
For those who don't want to download anything, check out Archive.org, you can use that to browse the MJNO archives too:

Although the archive at archive.org is from May 2007.
