User blog:BananaRamba/Auto-confirmed User?

So yesterday, I was looking around this Wiki, seeing if there was anything I could edit, and then went to my message wall and saw my account, nothing strange there, but when I looked I saw next to my profile, it said "Autoconfirmed User". I don't know what it means, so I hope someone could explain it to me... Or I could just look it up on Google, whatever works.
