Have the accounts in question fulfilled the emailconfirmed requirement?
That is, have they gone through the procedure that verifies that their
ownership of their email addresses? If you want a group for every user
who's logged in, MediaWiki comes with one called 'user'.
I need more complex user rights system , autopromote isn't working with all conditions
( APCOND_EMAILCONFIRMED,APCOND_EDITCOUNT, APCOND_AGE, APCOND_INGROUPS) email validation is
disabled so APCOND_EMAILCONFIRMED should be always true.
