San Diego Comic-Con is great for the lucky few that get to go, but millions of nerds around the world will be sitting at home sulking about missing it and stalking live tweets from panels. Luckily, Nerd HQ eases the pain of missing SDCC with their live streamed Conversations for a Cause.

“Heroes Reborn” star Zachary Levi started the event, which takes place at the New Children’s Museum in San Diego, in 2011 with his company, The Nerd Machine. Nerd HQ offers tickets to small, intimate panels with celebrities. The money goes to Operation Smile, a charity that helps children with cleft lip and palate repair surgeries. In its fifth year, Levi revealed that he hasn’t changed the event much.

“We’re bringing the same, and that’s kind of the point of Nerd HQ,” Levi told TV Insider. “I’m a big fan of keeping things simple and not fixing stuff that ain’t broken. Part of what we want to keep special is that we’re not competing with SDCC. We offer complimentary programming in a smaller, more interactive and personal setting. We don’t try to pack more or different into each year. ... That said, we listen to the people after each event and try to improve every part of the experience.”

While Nerd HQ itself is free, their Conversations for a Cause are not. Tickets are required to be in these small panels with stars from “Supernatural,” “Orphan Black” and more. For the most part, these panels sell out very quickly. Luckily, anyone around the world can watch on the Nerd Machine’s YouTube channel.

Below are a few of the most exciting panels that are happening during Nerd HQ, which is held July 21-24. We’ll definitely be live streaming these. (Note: All times are PDT. Adjust accordingly if you plan to watch the live streams.):
