Is it possible for the plugin to ask if the person who is connecting already has an account on the website? Then ask for the account details to connect accounts that use different usernames?
Then, if there is not already an account, I would like it to ask for a username and password to be created.
This seems to be a featured offered on many sites, I just cannot figure out how it is done.
If you know, even if it is a different plugin/method, let me know.
