I am an admin and bureaucrat on the Swedish Wikipedia with the nick Ternarius. I am also a global renamer. The easiest way to contact me is on my talk pages, either here on meta or on Wikipedia in Swedish.

Should you see any edits made by me on a Wikipedia version where I am no regular contributor, they are most likely due to my activity as a global renamer.

On Commons and English Wikipedia I am known as Ternarius, too.

I also understand Danish and Norwegian, but cannot write in them.

When addressed, I prefer the pronouns "they" and "their".
