update. seems to update 'Activity post' very slowly. took over a day...help help help
It seems that you don't really understand how activity works.
You can only get 14 (potential) activity per period ( Period = 2 weeks), which is the reason why it isn't going up anymore.
You already accumulated the max amount of activity you can get for this period. (14), (14 + 14), which means you participated/posted in 2 periods basically..
