I already have accounts on a bunch of Stack Exchange sites. Mostly when I'm looking at posting on a new SE site, I can see a blue 'Join this Community' button, which gives me a painless "extend my existing account to include this SE" experience. :+1:
E.g. (stolen from another question):
But on other Stack Exchange sites, I just get regular "Login / SignUp" buttons.
What's the deal here? Is that supposed to happen? Are some SE sites different? If I SignUp with the right credentials, will it all get joined together anyway? What happens if I use some variant of my email-address (e.g. gmail
vs googlemail
) will I be able to sync the accounts back together after the fact?
For reference, in this particular case it's the Super User SE, but I'm pretty sure I've seen this intermittently elsewhere.
