Did I understand correctly that currently, 109 users are merit sources?
I haven't noticed so many of them, at least not on the global part of the forum, I assume that most of them are from local boards.
Most Merit sources
[1] came with an average of less than 300 sMerit per month, there are about 5-6 with around 1000 sMerit, and the rest are between 250 and 100 or less, some of them are inactive or active in local baords.
I also think that @El duderino_ and some sources are more interested in WO so you don't notice many of them.
