infact if theymos most do that i wouldn't mind suggesting him to increase those who their allocations are very small and then remove those who are not active on the forum for about 3-8 plus.
They do not need to remove merit sources name increase the allocation of other merit source, it is better to have more merit sources instead. There have been many people that have applied for merit source but has not been chosen. But you are right that inactive sources should be removed but new people should be used to replace them.
