If you are on Twitter, and you decide to "follow" Simplifile, you will see a new county signing up with Simplifile just about every day. Sometimes two in a day, but about 4 each business week.
Now, to level set our expectations, MyEcheck is a choice for Simplifile customers, it is not a mandate. But I think in time, when Simplifile sees that MYEC is stable (they were an old client that dwindled after the 2008 banking disaster) and there is substantial cost savings, they will mandate it.
