Until now, I thought new SE sites can't get custom domain. But, look at an Area 51 proposal: Startup Business. It's in beta. Now, click visit button to visit the beta site. It has got custom domain host, custom brand & description. How?
What is meta?
- Any Stack Exchange user can ask a question
- The community provides support, votes on ideas, and reports bugs
- Your voice helps shape the way Stack Exchange operates
Right from your A51 proposal link in big bad bold letters:
What's Stack Exchange 1.0?
