All StackExchange proposals are handled over on Area 51.
Area 51 is the Stack Exchange Network staging zone. It’s where groups of experts come together to build new Q&A sites that work just like Stack Overflow. Here you can:
- Get involved in the process. Help sites get off the ground by defining what’s on- and off-topic, recruiting a critical mass of experts, and committing to the site’s success.
- Propose new Q&A sites. If you have an idea for an expert Q&A site, propose it here.
And there is already a proposal for a Real Estate site waiting for you to follow!
