Your main merit and your smerit do not decay and can never decay what will decay or disappear is that Smerit you will send out to someone who you think has a good contribution to the forum or someone who posted a thread you learnt something great from and so when you send the person the Smerit after 120 days that merit history or records will decay or disappear it won't be showing in that your merit history or records so don't get scared your merit and your smerit won't decay. And I will still advise you to go read about the forum I mean these are the things you should read and understand before any other thing in the forum.
