After the first 14 posts when you register an account on this forum, the activity will start counting 14 every 14 days.
Not nessceraily true.
Yesterday was the last week of a two-week activity period. Assume that you made your first post yesterday.
If you post 27 posts today, you can have 28 activity while you registered just yesterday.
Well I just noticed my activity just change now, so I guess its on every Thursday for me, that's two weeks from this Thursday my activity is going to change again.
The same activity periods are used for all users. Click
