Additionally on Rikafip comment. You can also install bpip.org chrome plugin extension so that you can easily browse your merit counts in 30, 60, 120 day period on your merit page in the forum as default to save you time from going in Bpip.org and manually search it.
This is the simplest way, because all you need to do is click on the tab
Profile -> Merit and there you can see your history of received and sent merits in the past 120 days.
This might not be the right thread for this but please pardon me and do well to let me know of the right thread So I can move it there.
To me, it seems more appropriate for the Meta board, but it is not a problem to post it here either, considering that there are certainly other
"beginners" who ask the same question.
