Sinkko.org and systemshed.com are private services for leisure use only. They contain pages of one regular Finnish family. We live in Helsinki, Finland.
These pages are mostly in Finnish, but note that some of the especially technical articles have a summary in English and examples, that can be understood without knowing any Finnish at all (like patching and compile scripts).
All of you looking for a genealogy info about Sinkko family, your should direct yourself to the “Sinkkojen sukuseura” pages. Unfortunately that’s all in Finnish.
You can reach the adminstrative person by writing email to sinkko.org for user kimmo.
2018 all the users except the admins have been deleted from the service. The registration and commenting features are not used anymore.
Cheers 🙂
