Following this tuto:

One of the steps is:
Need to look up whether the OpenID entered already belongs to an existing user on your site
My problem:
what's the OpenID like for a gmail account(I've no other OP account yet)? It seems to me that OpenID = https://www.google.com/accounts/o8/id for gmail, but how can I use that to look up since it's the same for all users?
