First, I apologize for me posting this here. I was hoping there would be a forum about website issues so to me this seem the next "best" choice.
Currently the checksum, MD5, is unavailable for SliTaz GNU/Linux Cooking 20140519 (42 Mb) - slitaz-RC-2.iso (link on http://www.slitaz.org/en/get/#cooking ) leading to http://mirror.switch.ch/ftp/mirror/slitaz/iso/RC-2/slitaz-RC-2.md5 which gives:
Error 404

It's always a relief for me to checksum (make comparison of) downloaded files, especially since my file downloader integrate that.
