- Open your forum's Domains tab and enter your domain (e.g.
forum.yoursite.com). - At your DNS provider, add the DNS records we show you in that tab — one routes your domain to our edge, one lets us issue and auto-renew its SSL.
- Wait for DNS to propagate (usually minutes, up to an hour). We detect it and issue SSL automatically.
- Once it shows Active, your forum is served on your domain over HTTPS — on the same global edge as the rest of the platform.
We point your forum's board URL at the custom domain for you, so links and emails use it. You can confirm it under ACP → Configuration → Settings → Site Details.
