Start a new private community?

Would my website visitors (and friends) be interested if I start a new private (invite-only) community, on this website? Topic would be anything worth your time (and mine): retro hardware, old Internet, Windows/Linux/macOS stuff, old software, music, movies, self hosting, solar, cyberpunk, promote your websites and ideas, personal projects, as long as it’s not politics and intentional baiting.

No identifiable data will be saved, no logs kept (spam would be pointless since the community would be private, and spamming would get your account removed anyway), I’m thinking about having a mandatory e-mail field on sign-up because I might want to contact you for explanations instead of just nuking your account. I won’t use the e-mail address for anything except that, no confirmations, validations, newsletters, spam, and after creating your account you can change it to something like a@a.com if you’re not interested in future e-mail conversations with me. Nobody else will see your e-mail address and if you change it after creating your account, the original address is no longer visible anywhere, or saved in any logs or databases.

I’m not interested in bringing phpBB or Discourse bloat into this, it will be a custom-made PHP8 “script” with nothing but categories, topics, replies and profiles. Data will get saved into a SQLite database, similar to the guestbook script. Since my website is pretty much compatible with most of the old web browsers anyway (except those that don’t like SVGs), the community part would be (and should be) browseable and usable on older machines too.

No files/images uploads, topics and replies would be Markdown-only with images and any HTML code stripped out. Keeping it as simple as possible.

Does it sound good? Bad? Insane? Batshit insane? Write me an e-mail if you want, or write in my guestbook about it.
