Is there a hook after user confirmation? I want to add a content type after a user registers to the site.

I tried hook_user_save() but it saves the content type before the user confirms his e-mail.

Is there a hook after e-mail confirmation?
Although this approach uses modules, I add nodes after users confirm their e-mails using Logintoboggan and Rules.  The Logintoboggan rules integration adds a new event, When the user account is validated, which will allow you to perform actions upon e-mail confirmation.
