Nice job, George... and jaustendesu
for the translation.
超元気なメンバー could simply be Active Member.
画期的なメンバー has always stood for Epoch-Making Member
George, maybe you should add two additional ones: 5000 and 10,000. The latter should be labeled "must be fluent" after the rumor started by misokatsu
a long time ago. As for the 5000, you need to come up with something....
Also, no YesJapan Staff badges? Poor Dave...
I also suggest doing a new achievement for members with many posts under the "Japanese Language & Study Discussion" forum. Kinzokusei no Inu
would easily sweep the competition
This is so people are encouraged to be active there.
On the downside, the achievements are now hidden and only visible under the member page. I understand that's done because of space constraints. However, maybe you can also have small stars for the course completion status. Someone who completed the first course would get one star and those who completed the 5 courses would get 5 stars. To remove any ambiguity, you can display it like that "Courses: ★ ★ ★" or similar... you can have different colors (silver and gold stars, for instance) for 70% and 100%, respectively.
