If you have an account on any other Stack Exchange site (Stack Overflow, tex.SE, math.SE, etc.), please make sure it is linked to your commitment to the OR site on Area 51.
Here's how to check:
- Visit the site proposal on Area 51.
- Under "Your Commitment", click on your user name.
- If it says "Unregistered User" at the top, you have not linked to another SE account.
- If it says "Registered User", click the tab that says "accounts". If you see your other accounts there, you have linked successfully; if not, you have not linked successfully.
Here's how to fix it: If you have another SE account but have not linked it successfully, it seems the easiest way to fix it is just to click "Uncommit", log in to your other SE account, and click "Commit" again. Alternately, you can try this.
Note: It can take up to a day for Area 51 to recognize your linked account. So, if you don't see the Commitment % roll over by 1 when you link your account, don't panic.
Why this is important: To move to the next phase (beta launch), sites need 100 or more committers who have 200 or more reputation points on other SE sites. This is often the hardest hurdle to cross.
