What is an advisor?

What exactly makes an advisor different from everyone else? Do they have extra responsibilites?

This is straight from the advisors page:

Who are advisors
Advisors are the official voice of Funadvice, and are users just like you and me. Users get promoted to advisors when they've either ranked highly by other users, or have just provided great answers.

How do I become an advisor?
You can become an advisor by first providing highly rated and clear answers. Contact us with a few of the answers you've provided and we'll consider upgrading your account to advisor status.

Many Advisors answer a question!
Yes, multiple advisors (and you) can answer a single question. The first advisor to answer the question will be considered the "official" advisor, and they will be promoted as such on the question page

Advisors also delete questions that are either duplicates or violate the terms of use.

They help make sure no one is breaking the terms of use. And if someone has to report abuse then they also take care of that too.
Basicly they just make sure everyone on this site is obeying the terms of use.

we delete questions and answers that break terms of use or are duplicates, edit titles to make them more understandable, move questions to the right catagories, report absusive users, delete inappropriate pictures, and we also (or atleast I do) get a lot of questions from newer members about the site or complaints about people being harassed...
