Now the proposal has moved to the Commitment phase. This means you personally commit to using the site - asking and answering questions - for a set period of time. As of writing this, the proposal has 11% of the commitments it needs to move to the beta phase. (There is not a set number needed, as they are weighted by a user’s reputation across the Stack Exchange sites. But because most of us don’t use Stack Exchange much, we’re going to need a lot of people.)
1. Go to the proposal.
2. Click Commit! in the upper left-hand corner of the page.
3. Supply your name, email, and a reason, as asked.
On behalf of all Unshelved Answers users, thanks again.
