I'm using joomla 2.5 and Community Builder 1.9

I have set that is not necessary to send an email to confirm de registration in joomla and the same in CB.

When someone use the CB Login module to register and after log in the web, the CB user is not confirmed, only if the user log in again. But the users recibe and email saying that needs to confirm the account by email. It's very strange.

Exist some plugin to syncronice automatically the joomla users with the CB users?
