It appears Tibia.de (which had moved to tibia.looki.de) has gone away permanently. This was the main reason I re-hosted the tutorials from there as they were really great and I didn't want them to be lost if something like this happened. Because the links in each of the tutorials are no longer valid, I would like to use this post to thank all the people who made them and gave me permission to host them here.
