Yes but let us say you are a beginner and post 23 posts in the 1st period and 5 posts in the 2nd period. Once the second period is complete, your activity will go up to 28. I
Will it?
I thought that wasnt the case and it was lost once the new period came in? It is lost only if you have missed an activity period (2 weeks) and haven't posted even once in that period. In that case, none of the extra posts made in the previous activity period are counted and you will not get any activity for the 2 week you have missed in between no matter how many posts you make in the new period after the one you missed. Otherwise, if you even make 1 post in that period, your account is assigned 14 activity points to be claimed any time in future by posting.
Can't remember where I have seen though. LoyceV can tell us perhaps since he is our Mr. Robot (copied from suchmoon).
Don't be dependent on anyone. It is not so difficult to find something that has been discussed by the forum officials themselves. Here, I did it for you:
