I've been able to sign up to different Stack Exchange sites by "linking" with my existing account, but I can't seem to do this for Super User.

I don't want to end up with different accounts and passwords and all the rest of it.

Can anyone help? Thanks.

(EDIT: Logging out and back in fixed it, but the answer still applies.)

  • Do you remember what the last time was you logged in and visited Super user? It could be that your cookies had expired.

  • @rene I'd never logged into to SU before. I may have visited the odd page before. However, I was technically still logged in to my other SE sites, but something may have gone off.

  • Okay, that could explain why logging out and back in fixed it, you have received new browser cookies for super user and all other SE domains by doing that.

You can join other Stack Exchange community, when you are already logged-in.

  1. Click on the Stack Exchange icon in the top bar, once the pop up is open, scroll down to find the "More Stack Exchange Communities" text box. Enter Super User in the text box and from the list click the link to open the superuser.com

  1. Now you can see the "Join the Community" button, clicking on the you can see another window

  1. Clicking on the "Confirm new account" will create a user account in Super User with your current credentials

  • I don't get the "Join This Community" button. I just get FaceBook or email login options. I was able to join this group, but not super user.

  • Doesn't work. It's in different domain, so apparently the cookies don't recognize me being logged eg. here.
