I was told it has to be 14 activity in two weeks... did something change?
Yeah that's true my friend told me about that.
14 posts in 2 weeks span.
Make 16 posts for next 2 weeks to make it 30 in total posts to qualify for jr. member rank.
Update will be done every Tuesday system time.
It works a bit differently. You can't get the activity higher than 14 in 2 weeks and higher than 28 in 4 weeks. So, as I understand, you need 6 weeks to become a Jr.member.
