How I can copy my Stack Overflow profile to all the sites of this network?
If you go to the accounts tab on your profile page - https://stackoverflow.com/users/720176/amit-dwivedi?tab=accounts you should see three links/buttons:
Copy Stack Overflow profile to all Stack Exchange accounts
Clear all Stack Exchange account associations
Copy Stack Overflow login credentials to all Stack Exchange sites.
Click on the first link.
If you want your Programmers information copying do the same but from your Programmers account - https://stackoverflow.com/users/720176/amit-dwivedi?tab=accounts
