I didn't hang around that site to long either, but it clearly said it publishes a newpaper in 12 languages. If he already publishes a newspaper in multiple languages, presumably he has sufficient number of translators on board. The site did mention that there were a number of translations of the "Poisonous Mushroom" were currently being worked on. At the very least there is an English translation and obviously the original German version. As there is an Estonian translation, then likely there would be a Finnish one too, and Russian as well if this translator is over 40. Being the USA, I don't think a Spanish version would be difficult to come by. Seems to me the reason that the Estonian version is highlighted on this site was because of the fact that it had drawn the attention of the Estonian Police, not because it was uniquely available in the Estonian language as implied by the Wikipedia article.
