We don’t offer memberships to specific OTAs.  Instead, we offer membership to NSTXL, which provides your firm access to all of our OTAs.  Currently, NSTXL is the consortium manager for three OTAs, TReX, S2MARTS, and SpEC, but we are bidding on many more.  As we manage more OTAs, there is no additional membership fee – just more opportunities for your firm to grow.
