Note I: For Hetalia I also tag characters as "aph *insert country here*, Nyotalia as *nyotalia*, and pairings by their pairing name, if I know them. I tag Madoka Magica characters too. "Madoka Kaname" "Homura Akemi" etc.
Note II: I only list the websites that I am active on / lurk / plan to be active on in the near future.
Note III: I use to tag my language log posts as "french log" and "lithuanian log" because I thought that they'd be seperate, but they never were so I switched over to the new tag instead. Older language log posts are tagged with both of the old tags (usually).
