I’m not exactly sure where this might go, or the best way to explain it.

I started using a plugin called RPXnow, so users can log in with their Google, Facebook, etc accounts. When they log in, it automatically creates an account for them. However, it uses their username from their Google account or whatever as their WP username too. Now, they can go in and change it in their profile to use their nickname or whatever they choose.

The problem is, if somebody leaves a comment as soon as they sign in, before they change their name in the profile, or add their URL or anything, that comment will use their ugly name instead of the nice name with their URL. What I am guessing is that the comment is stored in the database with whatever info was there when they commented, instead of linking to the user table so it has their name, URL, etc. Is this correct?
