I'm not sure how it works , but I guess as soon as the promotion is set , as soon as the requirements are met the promotion does its job , but what about the ones who already completed the requirements? Example:
A set a promotion for 5 minimum posts to get it. user gets 5 posts and gets the promotion , but does an old member of 100 posts gets it right away?
