As an autistic person, I'm much more comfortable with the classic forum layout. I know instantly where a certain discussion would be appropriate. Whereas on reddit, I often feel at bit lost to be frank even with flair on posts. I've created a youth rights forum on proboards.com It's a free hosting service for forums. My forum is called Youth Rights Now! Source: 7 months ago

I mean, sites like that have existed since back then. Hell Proboards is still active: https://proboards.com/. Source: about 1 year ago

Otherwise, your best bet is to use a 3rd party service (like proboards.com - I hope its ok I posted that link, im not affiliated with it) and then just link to it from your website. that would the less hassle way. Source: about 2 years ago

One idea I just remembered is to find a business co-founder that already knows a market well and sees an opportunity. Startup School's co-founder matching service is quite good. Source: almost 3 years ago
