Congratulations to the new Merit Source, now they are
83 
There are 83 merit sources with a total merit generation of up to 19100 sMerit per 30 days
Who are those "merit sources" and is it possible to become one of them? That is not the first time I hear about sources, but I nevr got any concrete information about them and terms of getting merits from those sources.
