Open Dental Forum

I'm ready to dive into Electronic Claim Submissions.
Has anybody used Post-N-Track? http://www.post-n-track.com/

I read that it is completely free and bypasses clearinghouses. How does Post-N-Track compare with Tesia or Claim Connect?
Can we integrate Post-N-Track into Open Dental?

We do list it as one of our compatible clearinghouses.
