there are so many users on this forum and any action that shall be handle by people will be a big problem, especially the merit amount is limited
This is a classical example of spam post the Merit system seeks to eradicate. What are you up about there with words, really? May I humbly inform you that apart from your post being a waste of data, it exemplifies a WAY NOT TO MERIT A POST.
Yes, the sMerit is limited but if I remember it correctly, I read somewhere that there might be a somewhat merit reset, where you will be given again the default sMerit base on your rank.
I am not sure it's about a reset. Perhaps you are referring to the
select Merited sources (also few too) I shall put up the link to that once I am hooked to it.
Edited: You may check this link.
