Well admin pays point on every month end if you have added signature today then admin will count post from today to month end date means you have added signature at 79 post and you have made 111 post as on date so admin will pay points for 79 post to 111 post.
I've got it.
But in my other sites I have their links on all my posts though I added just recently. I mean my signatures updated on all posts. How do they pay for that? Do they count from my 1sts posts because I have their posts in all my posts?
