Jeff Seidel is someone who tries to get American Jews visiting Israel to go to yeshiva. He says he'll pay for tickets. When I was at Hebrew University 15 years ago, he would have events in his French Hill center giving out free kosher Kentucky Fried Chicken and have a rabbi talk about marriage, sex, and relationships. He would also show TV shows and movies. I remember going there in the middle of the night to see Game 7 of the 2001 World Series when the Diamondbacks beat the Yankees in the first World Series to end in November (because of September 11). He's a short bald guy and doesn't really look like a rabbi.
I used to stay at the Heritage House for free in the Old City. They used to encourage people to study at Esh HaTorah if they stayed there. But when I wanted to take classes there after not having been in Israel for 4 years, the Heritage House said I'm too religious and Jeff Seidel wouldn't arrange somewhere to stay for free. The Heritage House was taken over by a guy who calls himself Packer (He's a rabbi but people just call him Packer.). He says he's the "Supreme Commander" and tries to be cool. It used to be more serious there. The Women's Heritage House still is the same but he destroyed the men's one. The women's one charges money now. Packer moved the men's one and it doesn't even list the address on his website. It's a shame because organizes trips to Judea and Samaria that the previous people in charge didn't do. I would always go to Judea and Samaria by myself but I remember Tel Shilo's visitor's center wasn't open so I couldn't see the archeological stuff there. An organized tour would be good for that but Packer's a moron. He actually is truly Right Wing but the way he runs his place is not good. He had a lot of Kahane books at his old Heritage House that he got from HaIvri.
The question about Meza is if he's Jewish or not. Obviously he's not a rabbi. My rabbi said that once someone converts through an Orthodox Bet Din, they will always be Jewish. If they sin, they're just like any other Jew. He told me the Shulchan Aruch said that when I brought up the issue of Ivanka Trump and mixed dancing and riding cars on Shabbat. Since Meza's not a rabbi, his conversions are fake, even if his own conversion is real. But if sends people to a real Bet Din, then they could be real converts. It's the Bet Din that does the conversion. People's personal rabbi just recommends to the Bet Din. He's not a kosher witness in a Bet Din since he does not keep Halacha so he couldn't testify before the Bet Din. Obviously he can't do a conversion on his own. Only Rabbinic judges do that. A Dayan (Rabbinic judge) is the highest level of Rabbinic ordination. Meza is not a rabbi so he's definitely not a dayan.
