- Follow the proposal. Yes, you need to log in, but the site uses OpenID so you don't even need to make a new username/password to do so.
- Submit some sample questions, good examples of what is on- and off-topic for a debate Q&A site
- Vote on sample questions, so we can refine the "vision" for the site
I already made my pitch for why I think this would be an excellent resource for the community, but I'll add this little bit. If you are an experienced debater or coach, think of how many times you've been asked the same set of questions by a new user or coach. Wouldn't it be nice if you could send them to a helpful website instead?
