那个规则是英文写的

activity = min(time * 14, posts)

活跃值 = 取最小值 （时间*14, 帖数）

time = number of two-week periods in which you've posted since your registration

这个时间就是 两周为一个周期， 而且这两周要发帖动作的才计数！

即注册后，按两周时间一算，这两周如果有发帖，就加一点，无发帖动作就不算！ 一个周期14点活跃值， 然后对比你这两周的发帖数，取最小值 为你的最终活跃值！！！所以要保持稳步增长的话，每两周发帖数要超过14最好~~~

应该是这个意思了吧~~·其余对应的等级活跃数，自己看吧~~~~

Brand New = activity = 0
Newbie = activity = 1
Jr. Member = activity = 30
Member = activity = 60
Full member = activity = 120

确实现在很适合入手，建仓了！
