Looks as though it just got started about 2 weeks ago.
Take care,

ETA: Not specifically 3rd-party, and I know that can make a difference from when I was attending Single Mothers by Choice thinkers/tryers meetings (believing I would be a single mom), and it was all about donor sperm, and the women doing IVF could barely get a word in edge-wise, and I was usually the only one doing DE, though of course several women needing DE joined just as I was getting pg. Always in the wrong place at the wrong time. But we all know that all IF patients are potential 3rd-party patients, a fact they may not like to consider, so hopefully there would be a place for you.
