IMO this is a good fit. There’s no rule against it, and I’m a fan of not splitting up communities until really necessary. Maybe once there’s so many people posting code for review that it becomes annoying to find other posts, then it’d be worth creating a new code review community or something.
Are you comfortable with handing over the lead mod role for each of the comics? I don’t know all the details, but I think being head mod affects certain mod actions? If you’re up for it, it seems like @[email protected] is taking over the daily posts here, and @[email protected] is taking over [email protected]. I’ve started posting the rest. One caveat is that I don’t think it’s a good idea to make the head mod someone on another instance, because cross-instance moderation actions can get weird sometimes.
