Hi all.
I'm the creator of the iOS app, kanji Flow. I'm going to be releasing an update that includes a lesson sharing feature along with the release of iOS 8. I'm trying to come up with a complete list of possible tags that users might want to use to tag their lessons when uploading. So far, I've got:
None
Adjectives
Adverbs
Anime
Business
Classical
Cooking
Counters
Explicit
Female
Food
Four Kanji
Grammar
Honorific
Humble
Idioms
Intransitive
JLPT N5
JLPT N4
JLPT N3
JLPT N2
JLPT N1
Male
Manga
Martial Arts
Math
Medical
Military
Movie
Nouns
Novel
Onomatopoeia
Phrases
Podcast
Poetry
Polite
Politics
Proverbs
Rude
Science
Sex
Slang
Technology
Television
Textbook
Time
Transitive
Verbs
Vocabulary
Kansai-ben
Kantou-ben
Kyoto -ben
Kyuushuu-ben
Nagano-ben
Osaka-ben
Ryuukyuu-ben
Tosa-ben
Touhouku-ben
Tsugaru-ben
I need this list to be as complete as possible when I release the new version because it will be very difficult to update at a later point without messing up all the lessons that have already been tagged.
So, I'd like to hear any recommendations you might have for word or lesson types that I may not have thought of yet.
Thanks a lot!

Thanks for the recommendations, Mike. These are definitely good categories. What kind of words do you imagine would appear in a Jargon or Special lesson?
