How can I preserve the forum vibe as it grows without gatekeeping?

I’ve been running a small hobby forum for a few years, and lately I’m struggling with how to handle the shift in tone when a community grows. What started as a tight-knit group where everyone knew each other now has a constant stream of new members, and the inside jokes and shared history that made it special are getting diluted. I don’t want to gatekeep, but I also miss the old vibe. Has anyone else managed to preserve that sense of community while scaling up?

I get the tug between growth and memory. Our forum went from a tight circle to a broader crowd, and the in-jokes started to feel exclusive. We tried an onboarding thread where new members answered a couple prompts and we started a monthly nostalgia roundup that links to classic threads and explains the backstory. It helped a bit with continuity, but the vibe is still looser than it used to be.

Early on we experimented with soft moderation that highlighted the context of old posts, hoping newcomers would get the mood quickly. It accidentally made conversations feel policed, and some long-time folks pushed back about 'teaching' new members. We dropped that approach after a few weeks.

Do you think the real issue is the volume, or that the signals for what counts as a good post have changed for newcomers?

One small thing I did last quarter was run a casual voice chat and invite folks to share what they loved about the old days. It drifted all over the place but ended with a few threads that felt authentic. Not a clean solution, but it reminded me to protect space while letting new voices in.
