Thank you for translating Userpage Plugin! This tool helps you sending translations to the developers.
Don't be discouraged by the amount of strings! If you don't feel like translating it all, just do a few strings and submit the translation. Each tiny step helps. Strings at top of the list are more important than those at the bottom, so please start at the top.
When you're done click the submit button. Your changes will be automatically submitted to the developers. You can find previous Japanese translation submissions here.
