Please don't, like, take this too far, but we have decided to sunset the main show.</p><p class="" data-rte-preserve-empty="true" style="white-space:pre-wrap;">Here's what we're going to do. Next week, on <strong>Sunday, July 6th</strong>, we're going to get together and we're going to record an episode. We would like to invite anybody who's interested in listening into one of our live recordings to come join us.</p><p class="" data-rte-preserve-empty="true" style="white-space:pre-wrap;">We're not sure what we're going to do. We thought about calling this our last episode, but that doesn't feel quite right. I think the three of us have some ideas about what we want the future of this show to look like, even if it's not recording an episode every week. We'll also be able to tell you a bit more about what happened last week.</p><p class="" data-rte-preserve-empty="true" style="white-space:pre-wrap;">We would love if you have thought about joining a recording session and haven't, or if you used to and you still kind of want to but you haven't had a good motivation, here's your motivation. Come party with us. (Hopefully it'll be a party.)</p><p class="" data-rte-preserve-empty="true" style="white-space:pre-wrap;">But yeah, so that's the news for this week. Next week we expect to put out, you know, a full like hour-long episode like usual, and then we'll... it's not going to look like our normal episodes. It'll be pretty talky. I mean, our episodes are always talky. Even this short episode is pretty talky. But we're, you know, we'll probably talk about the news a little bit, but it's mainly going to be, I don't know, almost like a brainstorming session, maybe. We'll find out.</p><p class="" data-rte-preserve-empty="true" style="white-space:pre-wrap;">You're invited and I would love to see, like me personally, I would love to see you. There are a bunch of names scrolling through my head right now. I would love to see everybody on that list. And I'm sure there are plenty of names that I don't know yet. And you know, that's one of the things that I'm most afraid of losing if we're not doing weekly episodes is all the new people I'm not going to get to meet.</p><p class="" data-rte-preserve-empty="true" style="white-space:pre-wrap;">Come on by next week, <strong>July, Sunday, the 6th. We record at 9 a.m. Pacific, 12 p.m. Eastern.</strong> If you aren't already in our discord, you can go to <a href="https://theorbitalmechanics.com/discord">theorbitalmechanics.com/discord</a>, and that'll just redirect you to an invite. Yeah, you got to have a discord account. I'm sorry. But come come join us and say hi.</p><p class="" data-rte-preserve-empty="true" style="white-space:pre-wrap;">All right, talk to you guys next week.
